ice: Enhanced IPv4 and IPv6 flow filter

Browse source 
Separate IPv4 and IPv6 ptype bit mask table into 2 tables:
with or without L4 protocols.

When a flow filter without any l4 type is specified, the
ICE_FLOW_SEG_HDR_IPV_OTHER flag can be used to describe if user
want to create a IP rule target for all IP packet or just IP
packet without l4 header.
