macvlan: add offload features for encapsulation
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. Signed-off-by: Dimitris Michailidis <dmichail@google.com> Signed-off-by: David S.
