Commit 093df73771ba ("scsi: qla2xxx: Fix Target mode handling with
Multiqueue changes.") introduces two bodies of code that look similar
but with s/req/rsp/ in the second instance. But in one case, it looks
like this conversion was missed.

of max queue pairs created. The number of max queue pairs created will
depend on number of MSI-X vector count.
This feature can be turned on via CONFIG_SCSI_MQ_DEFAULT or passing

A system can get hung task timeouts if a qlogic board fails during
initialization (if the board breaks again or fails the init). The hang
involves the scsi scan.
In a nutshell, since commit beb9e315e6e0 ("qla2xxx: Prevent removal and
board_disable race"):
...it is possible to have freed ha (base_vha->hw) early by a call to
qla2x00_remove_one when pdev->enable_cnt equals zero:
if (!atomic_read(&pdev->enable_cnt)) {
scsi_host_put(base_vha->host);
kfree(ha);
pci_set_drvdata(pdev, NULL);
return;
Almost always, the scsi_host_put above frees the vha structure
(attached to the end of the Scsi_Host we're putting) since it's the last
put, and life is good. However, if we are entering this routine because
the adapter has broken sometime during initialization AND a scsi scan is
already in progress (and has done its own scsi_host_get), vha will not
be freed. What's worse, the scsi scan will access the freed ha structure
through qla2xxx_scan_finished:
if (time > vha->hw->loop_reset_delay * HZ)
return 1;
The scsi scan keeps checking to see if a scan is complete by calling
qla2xxx_scan_finished. There is a timeout value that limits the length
of time a scan can take (hw->loop_reset_delay, usually set to 5
seconds), but this definition is in the data structure (hw) that can get
freed early.
This can yield unpredictable results, the worst of which is that the
scsi scan can hang indefinitely. This happens when the freed structure
gets reused and loop_reset_delay gets overwritten with garbage, which
the scan obliviously uses as its timeout value.
The fix for this is simple: at the top of qla2xxx_scan_finished, check
for the UNLOADING bit in the vha structure (_vha is not freed at this
point). If UNLOADING is set, we exit the scan for this adapter
immediately. After this last reference to the ha structure, we'll exit
the scan for this adapter, and continue on.
This problem is hard to hit, but I have run into it doing negative
testing many times now (with a test specifically designed to bring it
out), so I can verify that this fix works. My testing has been against a
RHEL7 driver variant, but the bug and patch are equally relevant to to
the upstream driver.

Recent commit 34393529163a ("be2net: fix MAC addr setting on privileged
BE3 VFs") allows privileged BE3 VFs to set its MAC address during
initialization. Although the initial MAC for such VFs is already
programmed by parent PF the subsequent setting performed by VF is OK,
but in certain cases (after fresh boot) this command in VF can fail.
The MAC should be initialized only when:
1) no MAC is programmed (always except BE3 VFs during first init)
2) programmed MAC is different from requested (e.g. MAC is set when
interface is down). In this case the initial MAC programmed by PF
needs to be deleted.
The adapter->dev_mac contains MAC address currently programmed in HW so
it should be zeroed when the MAC is deleted from HW and should not be
filled when MAC is set when interface is down in be_mac_addr_set() as
no programming is performed in this case.
Example of failure without the fix (immediately after fresh boot):
be2net 0000:01:00.0 eth0: Link is Up
...
be2net 0000:01:04.0: Emulex OneConnect(be3): VF port 0
During interface opening MAC address stored in netdev->dev_addr is
programmed in the HW with exception of BE3 VFs where the initial
MAC is programmed by parent PF. This is OK when MAC address is not
changed when an interfaces is down. In this case the requested MAC is
stored to netdev->dev_addr and later is stored into HW during opening.
But this is not done for all BE3 VFs so the NIC HW does not know
anything about this change and all traffic is filtered.
This is the case of bonding if fail_over_mac == 0 where the MACs of
the slaves are changed while they are down.
The be2net behavior is too restrictive because if a BE3 VF has
the FILTMGMT privilege then it is able to modify its MAC without
any restriction.
To solve the described problem the driver should take care about these
privileged BE3 VFs so the MAC is programmed during opening. And by
contrast unpriviled BE3 VFs should not be allowed to change its MAC
in any case.

If the device mac address is updated using ndo_set_mac_address(),
while the same mac address is already programmed, the driver does not
detect this condition if its netdev->dev_addr has been changed. The
driver tries to add the same mac address resulting in mac address
collision error. This has been observed in bonding mode-5 configuration.
To fix this, store the mac address configured in HW in the adapter
structure. Use this to compare against the new address being updated
to avoid collision.

Eachtime the ndo_set_rx_mode() routine is called, the driver programs the
multicast list in the adapter without checking if there are any changes to
the list. This leads to a flood of RX_FILTER cmds when a number of vlan
interfaces are configured over the device, as the ndo_ gets
called for each vlan interface. To avoid this, we now use __dev_mc_sync()
and __dev_uc_sync() API, but only to detect if there is a change in the
mc/uc lists. Now that we use this API, the code has to be-designed to
issue these API calls for each invocation of the be_set_rx_mode() call.

The be2net driver performs fw temperature queries on be_worker() routine,
which is executed each second for each be_adapter. There is a frequency
threshold to avoid fw query to happens at each call to be_worker();
instead, currently a fw query occurs once in 64 runs of the procedure.
Nevertheless, this fw temperature query is invoked only for adapters which
interface is up, so we can see I/O errors on read of hwmon counters from
userspace (from tools like lm-sensors) in case we have adapters' functions
which interface is down.
This patch moves the fw query code to be invoked even if interface is down.

On SR-IOV profiles, when the user connects a Linux Bridge or OVS to a BE3
vport, they suffer the "broadcast/multicast echo" problem. BE3 EVB echoes
broadcast and multicast packets back to PF's vport confusing the
Linux bridge. BE3 relies on the src-mac addr being programmed on the
interface to avoid sending back an echo of a broadcast or multicast packet
on a vPort. When a Linux bridge is connected to a BE3, the mac-addr of the
VM behind the bridge doesn't get configured on the vPort and so echo
cancellation doesn't work.
This patch worksaround this problem by disabling the EVB initially
and re-enabling it *only* when SR-IOV is enabled by the user. For the
driver fix to work, the BE3 FW version must be >= 11.1.84.0.

The symptom observed is multiple async handles get queued for same index
thus causing leak in buffers posted to FW.
The root cause is:
- async handle is continued to be used even if it does not match the
completion.
- list_move operation done on already filled index.
1. Remove use of writables, host_write_ptr and ep_read_ptr.
2. Remove consumed logic to update writables. Instead, use only
free_entries to do the accounting of handles to be posted back.
3. Remove busy_list, instead use simple slot to index handles.
4. Added check no data, header less and overflow to make sure
all async_handles are flushed in error cases.
5. Added code to verify gathering of handles to form PDU by
checking final bit before forwarding PDU.
6. Added code to catch mismatch with CQE and handle gracefully.
7. Use AMAP, traverse cri_wait_queue list to post buffers, log
"async PDU" related errors.
8. Rearranged few data structures and added comments in init &

In a similar fashion to how we handled exiting VLAN mode, move the logic
in i40e_vsi_add_vlan into i40e_sync_vsi_filters. Extract this logic into
its own function for ease of understanding as it will become quite
complex.
The new function, i40e_correct_mac_vlan_filters() correctly updates all
filters for when we need to enter VLAN mode, exit VLAN mode, and also
enforces the PVID when assigned.
Call i40e_correct_mac_vlan_filters from i40e_sync_vsi_filters passing it
the number of active VLAN filters, and the two temporary lists.
Remove the function for updating VLAN=0 filters from i40e_vsi_add_vlan.
The end result is that the logic for entering and exiting VLAN mode is
in one location which has the most knowledge about all filters. This
ensures that we always correctly have the non-VLAN filters assigned to
VID=0 or VID=-1 regardless of how we ended up getting to this result.
Additionally this enforces the PVID at sync time so that we know for
certain that an assigned PVID results in only filters with that PVID
will be added to the firmware.

The current flow for adding or updating the PVID for a VF uses
i40e_vsi_add_vlan and i40e_vsi_kill_vlan which each take, then release
the hash lock. In addition the two functions also must take special care
that they do not perform VLAN mode changes as this will make the code in
i40e_ndo_set_vf_port_vlan behave incorrectly.
Fix these issues by using the new helper functions i40e_add_vlan_all_mac
and i40e_rm_vlan_all_mac which expect the hash lock to already be taken.
Additionally these functions do not perform any state updates in regards
to VLAN mode, so they are safe to use in the PVID update flow.
It should be noted that we don't need the VLAN mode update code here,
because there are only a few flows here.
(a) we're adding a new PVID
In this case, if we already had VLAN filters the VSI is knocked
offline so we don't need to worry about pre-existing VLAN filters
(b) we're replacing an existing PVID
In this case, we can't have any VLAN filters except those with the old
PVID which we already take care of manually.
(c) we're removing an existing PVID
Similarly to above, we can't have any existing VLAN filters except
those with the old PVID which we already take care of correctly.
Because of this, we do not need (or even want) the special accounting
done in i40e_vsi_add_vlan, so use of the helpers is a saner alternative.
It also opens the door for a future patch which will refactor the flow
of i40e_vsi_add_vlan now that it is not needed in this function.

A future refactor of how the PF assigns a PVID to a VF will want to be
able to add and remove a block of filters by VLAN without worrying about
accidentally triggering the accounting for I40E_VLAN_ANY. Additionally
the PVID assignment would like to be able to batch several changes under
one use of the mac_filter_hash_lock.
Factor out the addition and deletion of a VLAN on all MACs into their
own function which i40e_vsi_(add|kill)_vlan can use. These new functions
expect the caller to take the hash lock, as well as perform any
necessary accounting for updating I40E_VLAN_ANY filters if we are now
operating under VLAN mode.

Fix a subtle issue with the code for converting VID=-1 filters into VID=0
filters when adding a new VLAN. Previously the code deleted the VID=-1
filter, and then added a new VID=0 filter. In the rare case that the
addition fails due to -ENOMEM, we end up completely deleting the filter
which prevents recovery if memory pressure subsides. While it is not
strictly an issue because it is likely that memory issues would result
in many other problems, we shouldn't delete the filter until after the
addition succeeds.

The current caller of i40e_update_filter_state incorrectly passes
aq_ret, an i40e_status variable, instead of the expected aq_err. This
happens to work because i40e_status is actually just a typedef integer,
and 0 is still the successful return. However i40e_update_filter_state
has special handling for ENOSPC which is currently being ignored.
Also notice that firmware does not update the per-filter response for
many types of errors, such as EINVAL. Thus, modify the filter setup so
that the firmware response memory is pre-set with I40E_AQC_MM_ERR_NO_RES.
This enables us to refactor i40e_update_filter_state, removing the need
to pass aq_err and avoiding a need for having 3 different flows for
checking the filter state.
The resulting code for i40e_update_filter_state is much simpler, only
a single loop and we always check each filter response value every time.
Since we pre-set the response value to match our expected error this
correctly works for all success and error flows.

Previous code refactors have accidentally caused issues with the
counting of active_filters. Avoid similar issues in the future by simply
re-counting the active filters every time after we handle add and delete
of all the filters. Additionally this allows us to simplify the check
for when we exit promiscuous mode since we can combine the check for
failed filters at the same time.
Additionally since we recount filters at the end we need to set
vsi->promisc_threshold as well.
The resulting code takes a bit longer since we do have to loop over
filters again. However, the result is more readable and less likely to
become incorrect due to failed accounting of filters in the future.
Finally, this ensures that it is not possible for vsi->active_filters to
ever underflow since we never decrement it.

The service task lock was being set in the scheduling function, not the
actual service task. This would potentially leave the bit set for a long
time before the task actually ran. Furthermore, if the service task
takes too long, it calls the schedule function to reschedule itself -
which would fail to take the lock and do nothing.
Instead, set and clear the lock bit in the service task itself. In the
process, get rid of the i40e_service_event_complete() function, which is
really just two lines of code that can be put right in the service task
itself.

Before this patch "ethtool -p" was not blinking the LEDs on boards
with 1G BaseT PHYs.
This commit identifies 1G BaseT boards as having the LEDs connected
to the MAC. Also, renamed the flag to be more descriptive of usage.
The flag is now I40E_FLAG_PHY_CONTROLS_LEDS.

The netdev->dev_addr MAC filter already exists in the
MAC/VLAN hash table, as it is added when we configure
the netdev in i40e_configure_netdev. Because we already
know that this address will be updated in the
hash_for_each loops, we do not need to handle it
specially. This removes duplicate code and simplifies
the i40e_vsi_add_vlan and i40e_vsi_kill_vlan functions.
Because we know these filters must be part of the
MAC/VLAN hash table, this should not have any functional
impact on what filters are included and is merely a code
simplification.

A previous commit 53cb6e9e8949 ("i40e: Removal of workaround for simple
MAC address filter deletion") removed a workaround for some
firmware versions which was reported to not be necessary in production
NICs. Unfortunately this workaround is necessary in some configurations,
specifically the Ethernet Controller XL710 for 40GbE QSFP+ (8086:1583).
Without this patch, the mentioned NICs with current firmware exhibit
issues when adding VLANs, as outlined by the following reproduction:
$modprobe i40e
$ip link set <device> up
$ip link add link <device> vlan100 type vlan id 100
$dmesg | tail
<snip>
kernel: i40e 0000:82:00.0: Error I40E_AQ_RC_EINVAL adding RX
filters on PF, promiscuous mode forced on
This results in filters being marked as FAILED and setting the device in
promiscuous mode.
The root cause of receiving the -EINVAL error response appears to be due
to a conflict with the default MAC filter which still exists on the
default firmware for this device. Attempting to add a new VLAN filter on
the default MAC address conflicts with the IGNORE_VLAN setting on the
default rule.

The i40e_txd_use_count function was fast but confusing. In the comments,
it even admits that it's ugly. So replace it with a new function that is
(very) slightly faster and has extensive commenting to help the thicker
among us (including the author, who will forget in a week) understand
how it works.
