mainline inclusion from mainline-v5.14-rc1 commit 2ba306627f59 category: feature bugzilla: NA CVE: NA DTS: DTS2021090315802
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Previously, with hardware limitation, the port VLAN filter are effective for both PF and its VFs simultaneously, so a single function is not able to enable/disable separately, and the VLAN filter state is default enabled. Now some device supports each function to bypass port VLAN filter, then each function can switch VLAN filter separately. Add capability flag to check whether the device supports modify VLAN filter state. If flag on, user will be able to modify the VLAN filter state by ethtool -K.
Furtherly, the default VLAN filter state is also changed according to whether non-zero VLAN used. Then the device can receive packet with any VLAN tag if only VLAN 0 used.
The function hclge_need_enable_vport_vlan_filter() is used to help implement above changes. And the VLAN filter handle for promisc mode can also be simplified by this function.
