Subject: [PATCH net-next 01/14] net: Remove MPLS GSO feature.
Date: Mon, 3 Nov 2014 22:00:51 -0800 [thread overview]
Message-ID: <1415080851-1652-1-git-send-email-pshelar@nicira.com> (raw)
Device can export MPLS GSO support in dev->mpls_features same way
it export vlan features in dev->vlan_features. So it is safe to
remove this redundant flag.
