4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Igor Russkikh <igor.russkikh@xxxxxxxxxxxx> [ 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.
