mainline inclusion from mainline-v5.12-rc1-dontuse commit bbfd4506f962e7e6fff8f37f017154a3c3791264 category: bugfix bugzilla: 173966 CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently, VF doesn't enable rx VLAN offload when initializating, and PF does it for VFs. If user disable the rx VLAN offload for VF with ethtool -K, and reload the VF driver, it may cause the rx VLAN offload state being inconsistent between hardware and software.
Fixes it by enabling rx VLAN offload when VF initializing.
