[dpdk-dev,06/12] net/bnxt: set MTU in dev config for jumbo packets
Checks
Commit Message
From: Qingmin Liu <qingmin.liu@broadcom.com>
MTU setting does not take effect after rte_eth_dev_configure
is called with jumbo enable unless it is configured using the
set_mtu dev_op.
Fixes: daef48efe5e5 ("net/bnxt: support set MTU")
