From 9f6e5886bcfdb3f95b925cdb9bd4e29dc41c2986 Mon Sep 17 00:00:00 2001 From: Igor Russkikh Date: Mon, 7 May 2018 16:10:38 +0300 Subject: [PATCH] net: aquantia: driver should correctly declare vlan_features bits In particular, not reporting SG forced skbs to be linear for vlan interfaces over atlantic NIC. With this fix it is possible to enable SG feature on device and therefore optimize performance. Reported-by: Ma Yuying Signed-off-by: Igor Russkikh Signed-off-by: David S.
