[PATCH net-next] macvlan: add offload features for encapsulation
From: Dimitris Michailidis <hidden>
Date: 2017-08-16 21:34:51
Currently macvlan devices do not set their hw_enc_features making encapsulated Tx packets resort to SW fallbacks. Add encapsulation GSO offloads to ->features as is done for the other GSOs and set ->hw_enc_features.
