Subject[PATCH 5.0 02/36] cxgb4: offload VLAN flows regardless of VLAN ethtype
Date
From: Raju Rangoju <rajur@chelsio.com>

[ Upstream commit b5730061d1056abf317caea823b94d6e12b5b4f6 ]

VLAN flows never get offloaded unless ivlan_vld is set in filter spec.
It's not compulsory for vlan_ethtype to be set.

So, always enable ivlan_vld bit for offloading VLAN flows regardless of
vlan_ethtype is set or not.

Fixes: ad9af3e09c (cxgb4: add tc flower match support for vlan)
