octeontx2-pf: Support to change VLAN based RSS hash options via ethtool
Add support to control rx-flow-hash based on VLAN.
By default VLAN plus 4-tuple based hashing is enabled.
Changes can be done runtime using ethtool
To enable 2-tuple plus VLAN based flow distribution
# ethtool -N <intf> rx-flow-hash <prot> sdv
To enable 4-tuple plus VLAN based flow distribution
# ethtool -N <intf> rx-flow-hash <prot> sdfnv
