[dpdk-dev] [DPDK] net/ice: fix flow rule checking

Wed Jan 27 10:42:36 CET 2021
Currently, when the RSS rule set to l4-src-only and l4-dst-only,
the hash value is different while the ingress packets
have same L4 parameters.
This patch keeps the hash value consistent in above situation.
Fixes: 38d632cbdc88 ("net/ice: refactor PF RSS")
Fixes: 0b952714e9c1 ("net/ice: refactor PF hash flow")
