From 4dc2437cdd6b6c6a745500ac647dc3cd66a0e2ee 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 [ Upstream commit 8c61ab7f111a2b29d051348b9cb9a39804ebf1f8 ] 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.
