Subject: net/ice: fix flow type selection for flow director
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=6e0fbe16dfc029aeaf6e1250e07f8c7619c87f2b;p=dpdk.git

net/ice: fix flow type selection for flow director

The FDIR parser will select ICE_FLTR_PTYPE_NONF_IPV4_OTHER as flow type
for an IPv4 UDP flow with empty l4 matching field which is not correct.
Same issues happens on all the combination between IPv4/IPv6 and
UDP/TCP/SCTP cases.

The patch fixes all the wrong flow ptype selections.

Fixes: f5cafa961fae ("net/ice: add flow director create and destroy")
