ice: Add new actions support for VF FDIR
Add two new actions support for VF FDIR:
A passthrough action does not specify the destination queue, but
just allow the packet go to next pipeline stage, a typical use
cases is combined with a software mark (FDID) action.
Allow specify a 2^n continuous queues as the destination of a FDIR rule.
Packet distribution is based on current RSS configure.
