Yes, well for the most part. This includes TX/RX with enhanced performance
(several patches already on ML but I need to review them), scatter/gather,
checksum offloads, packet type recognition, RSS, MAC/VLAN/promisc/allmulti
filtering and related configuration.

Actually, only secondary process support might be missing from the next
release. Since we're separately working on a new approach for mlx5, we'll
see how well it performs before considering a similar change for mlx4.
