Subject: [dpdk-dev] [PATCH v1] net: i40e: add VLAN tag size to RXMAX
Date: Mon, 31 Aug 2015 09:41:45 +0300 [thread overview]
Message-ID: <1441003305-24055-1-git-send-email-vladz@cloudius-systems.com> (raw)
HW requires it regardless the presence of the VLAN tag in the received frame.
Otherwise Rx frames are being filtered out on the MTU-4 boundary.
