i40e: Add support to program FDir SB rules for VF from PF through ethtool
With this patch we can now add Flow director Sideband rules for a VF from it's PF. Here is an example on how it can be done when VF id = 5 and queue = 2: "ethtool -N ethx flow-type udp4 src-ip x.x.x.x dst-ip y.y.y.y src-port p1 dst-port p2 action 2 user-def 5" User-def specifies VF id and action specifies queue.
