| Subject: net: aquantia: driver should correctly declare vlan_features bits |
| |
| From: Igor Russkikh <igor.russkikh@aquantia.com> |
| |
| [ 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. |
