net/mlx4_en: Add support for hardware accelerated 802.1ad vlan
To enable device support in accelerated 802.1ad vlan, the port capability "packet has vlan enable" (phv_en) should be set. Firmware won't work properly, in case phv_en is not set. The user can enable "phv_en" port capability with the new ethtool private flag phv-bit. The phv-bit private flag default value is OFF, users who are interested in 802.1ad hardware acceleration should turn ON the phv-bit private flag: $ ethtool --set-priv-flags eth1 phv-bit on Once the private flag is set, the device is ready for 802.1ad vlan acceleration. The user should also change the interface device features and turn on "tx-vlan-stag-hw-insert" which is off by default: $ ethtool -K eth1 tx-vlan-stag-hw-insert on "phv-bit" private flag setting is available only for Physical Functions(PF), the Virtual Function (VF) will be able to use the feature by setting "tx-vlan-stag-hw-insert" ethtool device feature only if the feature was enabled by the Hypervisor.
