Subject: [dpdk-dev] [PATCH] doc: add GRO API requirement in prog_guide
Date: Tue, 18 Dec 2018 12:25:19 +0800 [thread overview]
Message-ID: <1545107119-85376-1-git-send-email-jiayu.hu@intel.com> (raw)
The GRO library requires that applications set correct values for
MBUF->l2_len/l3_len/l4_len/outer_l2_len/outer_l3_len/pkt_len/data_len.
This patch adds the requirement in prog_guide.
