support matching on GRE key and present bits (C,K,S)
example testpmd command could be:
testpmd>flow create 0 ingress group 1 pattern eth / ipv4 /
gre crksv is 0x2000 crksv mask 0xb000 /
gre_key key is 0x12345678 / end
actions rss queues 1 0 end / mark id 196 / end
Which will match GRE packet with k present bit set and key value is
0x12345678.
