Subject: [dpdk-dev] net/ice: fix error setting for L2TAG
Date: Wed, 20 May 2020 17:46:14 -0400 [thread overview]
Message-ID: <20200520214614.34513-1-jia.guo@intel.com> (raw)
Base on HW, if a packet be split into multiple segments, the L2TAG
should only be valid on the last Rx descriptor. So fix it by setting
L2TAG into mbuf when processing the last split packet.
Fixes: c68a52b8b38c ("net/ice: support vector SSE in Rx")
