Subject: net/i40e: fix filter pctype
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=11b58ac709690cb4086a0a01f979b3d3f8ea7d21;p=dpdk.git

net/i40e: fix filter pctype

The i40e_filter_pctype TCP_SYN_NO_ACK, UNICAST_IPV4_UDP and
MULTICAST_IPV4_UDP for x722 were missing when translating RSS type to
i40e_filter_pctype. This patch fixes it.

Fixes: da7018ec29d4 ("net/i40e: fix queue region in RSS flow")
