Subject: [dpdk-dev] [PATCH 08/10] net/ice/base: choose TCP dummy packet by protocol
Date: Thu, 11 Jun 2020 16:43:28 +0800
Message-ID: <20200611084330.18301-9-qi.z.zhang@intel.com> (raw)
In-Reply-To: <20200611084330.18301-1-qi.z.zhang@intel.com>

In order to find proper dummy packets for switch filter,
it need to check ipv4 next protocol number, if it is 0x06,
which means next payload is TCP, we need to use TCP
format dummy packet.
