[Intel-wired-lan] [next PATCH S7 1/9] i40e: fix incorrect ethtool statistics veb and veb.tc_

[Intel-wired-lan] [next PATCH S7 1/9] i40e: fix incorrect ethtool statistics veb and veb.tc_

[Alice Michael]

From: Dmitrii Golovanov <dmitrii.golovanov@intel.com>

This patch fixes missing call of i40e_update_veb_stats() in function
i40e_get_ethtool_stats() to update stats data of VEB and VEB TC
counters before they are written into ethtool buffer.
Before the patch ethtool counters may fell behind interface counters.

[Intel-wired-lan] [next PATCH S7 2/9] i40e: make visible changed vf mac on host

[Alice Michael]

From: Aleksandr Loktionov <aleksandr.loktionov@intel.com>

This patch makes changed vm mac address visible on host via
ip link show command. This problem is fixed by copying last
unicast mac filter to vf->default_lan_addr.addr. Without
this patch if vf mac was not set from host side and
if you run ip link show $pf, on host side you'd always
see a zero mac, not the real vf mac that vf assigned to
itself.

[Intel-wired-lan] [next PATCH S7 4/9] i40e: don't report link up for a VF who hasn't enabled queues

[Alice Michael]

From: Jacob Keller <jacob.e.keller@intel.com>

Commit d3d657a90850 ("i40e: update VFs of link state after
GET_VF_RESOURCES") modified the PF driver to notify a VF of
its link status immediately after it requests resources.

This was intended to fix reporting on VF drivers, so that they would
properly report link status.

However, some older VF drivers do not respond well to receiving a link
up notification before queues are enabled. This can cause their state
machine to think that it is safe to send traffic. This results in a Tx
hang on the VF.

More recent versions of the old i40evf and all versions of iavf are
resilient to these early link status messages. However, if a VM happens
to run an older version of the VF driver, this can be problematic.

Record whether the PF has actually enabled queues for the VF. When
reporting link status, always report link down if the queues aren't
enabled. In this way, the VF driver will never receive a link up
notification until after its queues are enabled.

[Intel-wired-lan] [next PATCH S7 9/9] i40e: Remove unicast log when VF is leaving multicast mode.

[Alice Michael]

From: Czeslaw Zagorski <czeslawx.zagorski@intel.com>

This patch removes unicast log when VF is leaving multicast mode.
Added check of vf->vf_states &
I40E_VF_STATE_MC_PROMISC/I40E_VF_STATE_UC_PROMISC.
Without this commit, leaving multicast mode logs "unset unicast"
in dmsg.
