> Similar to changes done to the PF driver in commit 6622f5cdbaf3 ("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.
