net/ice/base: packet encapsulation for RSS

RSS configurations calls currently support only non-tunneled packets,
which uses outer-first IPs. Adding another call to configure RSS for
tunneled packets which will enable hashing on inner-last IP. RSS hash
will only be done on the innermost IP.
- Update RSS configuration calls to take packet segment count as input
  argument
- Update flow profile ID to include identifier for encapsulated packet
  [0:31] : Packet match fields
  [32:62]: Protocol header header
  [63]: Encapsulation flag, 0 if non-tunneled, 1 if tunneled
