Subject: [PATCH] net: aquantia: driver should correctly declare vlan_features bits
Git-commit: 8c61ab7f111a2b29d051348b9cb9a39804ebf1f8
Patch-mainline: v4.17-rc5
References: bsc#1051510

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.
