Subject: net/mlx5e: Add VLAN offload features to hw_enc_features
Patch-mainline: v4.17-rc1
Git-commit: 71186172b71fe7266eaa768f028c20725202dfd5
References: bsc#1103990 FATE#326006

We support outer VLAN offload in driver and HW regardless of whether
an encapsulation is present in the next headers.

Exposing this in hw_enc_features will allow us to offload outer VLANs
in cases where encapsulation protocols like VXLAN and IPsec are used.
