      i40evf: Make VF reset warning message more clear · 693acdd0
      由 Harshitha Ramamurthy 提交于 
      When the PF resets the VF, the VF puts out a warning message
indicating that the VF received a reset message from the PF.
Make this message more clear so that we do not mistakenly
think that the PF is undergoing a reset.

      i40evf: use __dev_[um]c_sync routines in .set_rx_mode · 8946b563
      由 Jacob Keller 提交于 
      Similar to changes done to the PF driver in commit 6622f5cd ("i40e:
make use of __dev_uc_sync and __dev_mc_sync"), replace our
home-rolled method for updating the internal status of MAC filters with
__dev_uc_sync and __dev_mc_sync.

These new functions use internal state within the netdev struct in order
to efficiently break the question of "which filters in this list need to
be added or removed" into singular "add this filter" and "delete this
filter" requests.

This vastly improves our handling of .set_rx_mode especially with large
number of MAC filters being added to the device, and even results in
a simpler .set_rx_mode handler.

Under some circumstances, such as when attached to a bridge, we may
receive a request to delete our own permanent address. Prevent deletion
of this address during i40evf_addr_unsync so that we don't accidentally
stop receiving traffic.

      i40e: i40e: Change ethtool check from MAC to HW flag · 7b63435a
      由 Dave Ertman 提交于 
      The MAC, FW Version and NPAR check used to determine
if shutting off the FW LLDP engine is supported is not
using the usual feature check mechanism.

This patch fixes the problem by moving the feature check
to i40e_sw_init in order to set a flag in pf->hw_features
that ethtool will use for priv_flags disable operation.

      i40e: do not force filter failure in overflow promiscuous · 7363115e
      由 Alan Brady 提交于 
      Broadcast filters can now cause overflow promiscuous to trigger when
adding "too many" VLANs to all the ports of a device and the driver
needs a way to exit overflow promiscuous once triggered.

Currently the driver looks to see if there are "too many" filters and/or
we have any failed filters to determine when it is safe to exit overflow
promiscuous.  If we trigger overflow promiscuous with broadcast filters,
any new filters added will be "auto-failed" until we exit overflow
promiscuous.  Since the user can't manually remove the failed broadcast
filters for VLANs (nor should we expect the user to do such), there is
no way to exit overflow promiscuous without reloading the driver.

The easiest way to do this is to remove the shortcut to "auto-fail"
filters in overflow promiscuous.  If the user removes the VLANs, the
failed filters will be removed and since we're no longer "auto-failing"
new filters, we'll eventually get a good set of filters and exit
overflow promiscuous.

This has the side benefit of making filter state more explicit in that
if a filter says it's failed we know for a fact it failed and not just
assuming it will if we're in overflow promiscuous.  This is nice because
if the user removes some filters and then adds some, even if we're in
overflow promiscuous, the filter might succeed; we were just assuming it
won't because the user hasn't rectified other existing failed filters.

      i40e: refactor promisc_changed in i40e_sync_vsi_filters · cc6a96a4
      由 Alan Brady 提交于 
      This code here is quite complex and easy to screw up.  Let's see if we
can't improve the readability and maintainability a bit.  This refactors
out promisc_changed into two variables 'old_overflow' and 'new_overflow'
which makes it a bit clearer when we're concerned about when and how
overflow promiscuous is changed.  This also makes so that we no longer
need to pass a boolean pointer to i40e_aqc_add_filters.  Instead we can
simply check if we changed the overflow promiscuous flag since the
function start.
