From: Eran Ben Elisha <era...@mellanox.com>
When the underlying device supports offloads encapulated traffic,
we need to reflect that through the hw_enc_features field of the
team net-device.
This will cause the xmit path in the core networking stack to provide
team with encapsulated GSO frames to offload into the HW etc.
Using this over Mellanox ConnectX3-pro (mlx4 driver) card that supports
VXLAN offloads we got 36.0 Gbits/sec using eight iperf streams.
