Subject: [dpdk-dev] [PATCH v4 08/19] net/hinic: add fdir validate flow operations
Date: Thu, 10 Oct 2019 22:51:52 +0800
Message-ID: <a4749ba6ab496654b9eecc8a1ff5815f5fde703a.1570718029.git.cloud.wangxiaoyun@huawei.com> (raw)
In-Reply-To: <cover.1570718029.git.cloud.wangxiaoyun@huawei.com>

This patch is to validate the filter rules, which includes
ntuple filter, ethertype filter and fdir filter. The packets
type that supported are BGP,VRRP,LACP,ARP and ICMP.
