Subject: [dpdk-dev] [PATCH v2 5/5] net/iavf: fix max mtu size packets with vlan tag cannot be received by default
Date: Tue, 22 Sep 2020 01:23:38 +0000
Message-ID: <20200922012338.11277-6-stevex.yang@intel.com> (raw)
In-Reply-To: <20200922012338.11277-1-stevex.yang@intel.com>
testpmd will initialize default max packet length to 1518 which doesn't
include vlan tag size in ether overheader. Once, send the max mtu length
packet with vlan tag, the max packet length will exceed 1518 that will
cause packets dropped directly from NIC hw side.
iavf can support dual vlan tags that need more 8 bytes for max packet size,
so, configures the correct max packet size in dev_config ops.
Fixes: 02d212ca3125 ("net/iavf: rename remaining avf strings")
