Subject: net/ice: add flow IPv6 TC support
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=72d138ff0f58d2cf2c3ef58b0f5c32e186b82a15;p=dpdk.git

net/ice: add flow IPv6 TC support

When set flow ipv6 tc rule, ice_get_flow_field will set error.
This patch fixes this issue.

Fixes: d76116a4678f ("net/ice: add generic flow API")
