> Subject: [Intel-wired-lan] [PATCH] i40e: Add macvlan support on i40e
>
> This patch enables macvlan offloads on Fortville devices. The idea is to use
> channels as macvlan interfaces. The channels are VSIs of type VMDQ. When
> the first macvlan is created, the maximum no. 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 the macvlan:
> 1. sudo ethtool -K ens261f1 l2-fwd-offload on 2. ip link add link ens261f1
> name macvlan1 type macvlan 3. sudo ip link add link ens261f1 name macvlan1
> type macvlan 4. sudo ip link set macvlan1 up
