Subject: [dpdk-dev] net/i40e: fix vlan packets drop
Date: Mon, 14 Oct 2019 15:53:52 +0800 [thread overview]
Message-ID: <1571039632-5524-1-git-send-email-xiao.zhang@intel.com> (raw)
vlan packets with ip length bigger then 1496 will not be received by
i40e due to wrong packets size checking. This patch fixes the issue by
correcting the maximum frame size during checking.
Fixes: 35b2d13fd6fd ("net: add rte prefix to ether defines")
