they're no big deal. To assist in assessing this, add a counter to

problem. A large, ever-growing number indicates that Something Bad is

In some modes, bonding would not enslave VF interfaces. This is due to
bonding calling change_mtu and the immediately calling open. Because of
the asynchronous nature of the admin queue mechanism, the VF returns
-EBUSY to the open call, because it knows the previous operation hasn't
finished yet. This causes bonding to fail with a less-than-useful error
message.
To fix this, remove the check for pending operations at the beginning of
open. But this introduces a new bug where the driver will panic on a
quick close/open cycle. To fix that, we add a new driver state,
__I40EVF_DOWN_PENDING, that the driver enters when down is called. The
driver finally transitions to a fully DOWN state when it receives
confirmation from the PF driver that all the queues are disabled. This
allows open to complete even if there is a pending mtu change, and
bonding is finally happy.

This patch fixes the Hash PCTYPE enable for X722 since it supports
a broader selection of PCTYPES for TCP and UDP.
This patch also fixes a bug in XL710, X710, X722 support for RSS,
as of now we cannot reduce the (4)tuple for RSS for TCP/IPv4/IPV6 or
UDP/IPv4/IPv6 packets since this requires a product feature change
that comes in a later release.
A VF should never be allowed to change the tuples for RSS for any
PCTYPE since that's a global setting for the device in case of i40e
devices.

If the driver calls skb_set_hash even with a zero hash, that
indicates to the stack that the hash calculation is offloaded

for load balancing if the user decides to turn of rx-hashing
on our device.
This patch fixes the path so that we do not call skb_set_hash
if the feature is disabled.

If the driver were to happen to have a mutex held while

then do the same work only once in probe/remove.

follow the change correctly. This now cleans the whole list rather
that just part of the first element.

can happen when enabling a bunch of VFs and the VF driver is not
blacklisted.
Since these messages are really for debugging purposes, reclassify
them as such.

When VFs are created, the MAC address defaults to all zeros, indicating
to the VF driver that it should use a random MAC address. However, the
PF driver was incorrectly adding this zero MAC to the filter table,
along with the VF's randomly generated MAC address.
Check for a good address before adding the default filter. While we're
at it, make the error message a bit more useful.

The separate functions to gather Flow control Rx XOFF stats was to
determine if the Tx for a queue was paused due to Link Flow Control(LFC)
or Priority Flow Control(PFC).
But, with recent change in the i40e driver the logic for checking th Tx
hang has been removed and these functions don't do anything meaningful.
Hence, there is no need to keep these separate functions to gather Rx
XOFF stats for LFC or PFC.
This patch removes these functions and moves the stat collection for
XOFF Rx to the i40e_update_pf_stats() that collects all the PF stats.

Ethtool priv flags implementation to enable or disable packet split, which
is a hardware feature that inspects headers and will put headers in a
separate DMA buffer from the payload data. The driver was automatically
choosing to enable packet split in some cases and this gives the user the
ability to turn it off/on explicitly.
to query state:
ethtool --show-priv-flags ethx
to enable:
ethtool --set-priv-flags ethx packet-split on
to disable:
ethtool --set-priv-flags ethx packet-split off
Why would anyone want this?
Because some environments benefit from header/data split in the receive
buffer, and the driver defaults to one or the other depending on
environment/kernel parameters.
Why didn't you implement a generic ethtool control for this feature?
Because Intel hardware is the only hardware that supports header/data
split.

i40e_sync_vsi_filters() is the surly teenager of this driver. It says
it's going to report errors, but it doesn't actually do that most of the

Change this function to have a common exit point so it will properly
release the busy lock on the VSI. Propagate errors to the callers.
Finally, adjust a few callers to check for and deal with errors from
this function.

This patch fixes the memory leak which would be seen otherwise when user
programs flow-director filter using ethtool (sideband filter programming).
When ethtool is used to program flow directory filter, 'raw_buf' gets
allocated and it is supposed to be freed as part of queue cleanup. But
check of 'tx_buffer->skb' was preventing it from being freed.

This patch contains following changes:
- detection and recovery logic (issue SW interrupt) has been moved to
service_task from timeout function.
- added some more debug info from tx_timeout.
Logic to detect and recover TX queue hung is now two step process:
- service_task detects TX queue hung and sets a bit(hung_detected) if
it was not set.
- if bit was set (means this is back-back hung condition detected),
issue SW interrupt and clear the bit.
- napi_poll clears the bit unconditionally since it cleans TX/RX queues.

This patch fixes an issue where adminq init failures always provided
a message that NVM was newer than expected. This is not always the
case for init_adminq failures. Without this patch, if adminq init
fails for any reason, newer NVM message would be given. This
problem is fixed by adding a check for that specific error
condition and a different hopefully helpful message otherwise.

This patch fixes the issue of forcing WB too often causing us to not
benefit from NAPI.
Without this patch we were forcing WB/arming interrupt too often taking
away the benefits of NAPI and causing a performance impact.
With this patch we disable force WB in the clean routine for X710
and XL710 adapters. X722 adapters do not enable interrupt to force
a WB and benefit from WB_ON_ITR and hence force WB is left enabled
for those adapters.
For XL710 and X710 adapters if we have less than 4 packets pending
a software Interrupt triggered from service task will force a WB.
This patch also changes the conditions for setting RS bit as described
in code comments. This optimizes when the HW does a tail bump amd when
it does a WB. It also optimizes when we do a wmb.

When a lot (many hundreds) of MAC or VLAN filters are added at one time,
we can overflow the Admin Queue buffer size with all the requests.
Unfortunately, the driver would then calculate the message size
incorrectly, causing it to be rejected by the PF. Furthermore, there was
no mechanism to trigger another request to allow for configuring the
rest of the filters that didn't fit into the first request.
To fix this, recalculate the correct buffer size when we detect the
overflow condition instead of just assuming the max buffer size. Also,
don't clear the request bit in adapter->aq_required when we have an
overflow, so that the rest of the filters can be processed later.

The watchdog only calls link_event not handle_link_event which means
that we need to save the old information in link_event.
Previously when polling we were comparing current data to the old data
saved the last time we actually received a link event. This means that
the polling would only fix link status changes in one direction
depending on what the last old data saved off was.

There's really no reason to kill the kernel thread just because of a

assure that the string is never too long, and WARN_ON to still put out
a warning that we might want to look at the feature list length.

This code is pretty confused. The variable name 'bytes_not_copied'
clearly indicates that the programmer knew the semantics of
copy_{to,from}_user, but then the return value is checked for being
negative and used as a -Exxx return value.
I'm not sure this is the proper fix, but at least we get rid of the
dead code which pretended to check for access faults.
