> This patch enables macvlan offloads for i40e. The idea is to use channels as
> macvlan interfaces. The channels are VSIs of type VMDQ. When the first
> macvlan is created, the maximum number of channels possible are created.
> From then on, as a macvlan interface is created, a mac filter is added to these
> already created channels (VSIs).
> 
> This patch builds on top of the recent changes which move away from the
> select_queue implementation of picking the tx queue.
> 
> Steps to configure macvlan offloads:
> 1. ethtool -K ens261f1 l2-fwd-offload on 2. ip link add link ens261f1 name
> macvlan1 type macvlan 3. ip addr add <address> dev macvlan1 4. ip link set
> macvlan1 up
