When I was adding the code for enabling VLAN promiscuous mode with SR-IOV
enabled I had inadvertently left the VLNCTRL.VFE bit unchanged as I has
assumed there was code in another path that was setting it when we enabled
SR-IOV. This wasn't the case and as a result we were just disabling VLAN
filtering for all the VFs apparently.
Also the previous patches were always clearing CFIEN which was always set
to 0 by the hardware anyway so I am dropping the redundant bit clearing.

Several areas of ixgbe were written before widespread usage of the
BIT(n) macro. With the impending release of GCC 6 and its associated new
warnings, some usages such as (1 << 31) have been noted within the ixgbe
driver source. Fix these wholesale and prevent future issues by simply
using BIT macro instead of hand coded bit shifts.
Also fix a few shifts that are shifting values into place by using the
'u' prefix to indicate unsigned. It doesn't strictly matter in these
cases because we're not shifting by too large a value, but these are all
unsigned values and should be indicated as such.

This brings the logic closer to how we handle the stats in ixgbe and it
sets us up for introducing per-queue stats.
Use IXGBEVF_STAT and IXGBEVF_NETDEV_STAT for accessing the driver and
netdev stats respectively. This way we don't have to calculate the
stats based on register values which could lead to the counters not
being initialized properly when the interface is down.
IXGBEVF_QUEUE_STATS_LEN is set to include the number of queues.
Also some defines were renamed to use the IXGBEVF prefix.

This field is used to record the RX queue index for a redirect action
passed via ring_cookie field in struct ethtool_rx_flow_spec which is
a u64 value.
For ex: after adding a filter rule to redirect to a VF using ethtool
# echo 4 > /sys/class/net/p4p1/device/sriov_numvfs
# ethtool -N p4p1 flow-type ip4 src-ip 192.168.0.1 action 0x100000000
querying for the rule shows the Action as 'Direct to queue 0'
# ethtool -n p4p1
4 RX rings available
Total 1 rules
Filter: 2045
Rule Type: Raw IPv4
Src IP addr: 192.168.0.1 mask: 0.0.0.0
Dest IP addr: 0.0.0.0 mask: 255.255.255.255

L4 bytes: 0x0 mask: 0xffffffff
VLAN EtherType: 0x0 mask: 0xffff
VLAN: 0x0 mask: 0xffff
User-defined: 0x0 mask: 0xffffffffffffffff
Action: Direct to queue 0
With this fix, ethtool will report the right queue index even for VFs.
Action: Direct to queue 4294967296
Here 4294967296 corresponds to 0x100000000.
We need to update 'ethtool' to report the queue index as a Hex value so
that it is more user friendly and matches with the 'action' value that
is passed when adding the rule.

X550EM_a/x did not have a default value for mac->ops.setup_link which

This patch sets mac->ops.setup_link to ixgbe_setup_mac_link_X540 for
X550EM_a/x which is also default for X550. This will result in
mac->ops.setup_link calling the link setup function for the respective

Previously the PF driver would only set VLAN spoof checking if
the VF had created VLANs. This was done by setting and checking
a counter (vlan_count) whenever a VLAN was created by the VF.
However it is possible for the vlan_count to be !=0 while there are
no VLANs assigned to the VF due to the count incrementing every
time a VLAN 0 is added on ifdown/up, which resulted in VLAN spoofing
always being set for those VFs.
This patch cleans up the logic by unconditionally setting VLAN based on
how the VF is configured (via ip link set ethX vf Y spoofchk on/off).
This change also resolves an issue where the VLAN spoofing can remain
set even after being disabled by the user due to the driver enabling
VLAN spoof checking every time a VLAN is added to the VF, but would
only allow changes in the setting if vlan_count != 0.
Also default_vf_vlan_id and vlans_enabled were removed from the
vf_data_storage structure since they are not being used in the driver.

Change ixgbe_set_mac_anti_spoofing() to set MAC spoofing per VF similar

only disable MAC spoof checking when creating MACVLAN.

Since the network driver and RDMA driver operate on the same PCI function,
we need to create an interface to allow the RDMA driver to share resources
with the network driver.
1. Create a new bnxt_en_dev struct which will be returned by
bnxt_ulp_probe() upon success. After that, all calls from the RDMA driver
to bnxt_en will pass a pointer to this struct.
2. This struct contains additional function pointers to register, request
msix, send fw messages, register for async events.
3. If the RDMA driver wants to enable RDMA on the function, it needs to
call the function pointer bnxt_register_device(). A ulp_ops structure
is passed for RCU protected upcalls from bnxt_en to the RDMA driver.
4. The RDMA driver can call firmware APIs using the bnxt_send_fw_msg()
function pointer.
5. 1 stats context is reserved when the RDMA driver registers. MSIX
and completion rings are reserved when the RDMA driver calls
bnxt_request_msix() function pointer.
6. When the RDMA driver calls bnxt_unregister_device(), all RDMA resources
will be cleaned up.

The VF link state can be changed via the 'ip link set' cmd.
Currently, the new link state does not take effect immediately.
The fix is for the PF to send a link change async event to the
designated VF after a VF link state change. This async event will
trigger the VF to update the link status.

After generating the random MAC address for VF, call the firmware to
approve it. This step serves 2 purposes. Some hypervisor (e.g. ESX)
wants to approve the MAC address. 2nd, the call will setup the
proper forwarding database in the internal switch.
We need to unlock the hwrm_cmd_lock mutex before calling bnxt_approve_mac().
We can do that because we are at the end of the function and all the
previous firmware response data has been copied.

The existing code is inconsistent in reporting and accepting the combined
channel count. bnxt_get_channels() reports maximum combined as the
maximum rx count. bnxt_set_channels() accepts combined count that
cannot be bigger than max rx or max tx.
For example, if max rx = 2 and max tx = 1, we report max supported
combined to be 2. But if the user tries to set combined to 2, it will
fail because 2 is bigger than max tx which is 1.
Fix the code to be consistent. Max allowed combined = max(max_rx, max_tx).
We will accept a combined channel count <= max(max_rx, max_tx).

may now be staged into the "update" area of the NVM and subsequently
verified and installed by the firmware using the newly introduced

NVM-resident package installation log contains valid time-stamps.
