[dpdk-dev] [PATCH 7/8] net/bnxt: cleanups in MTU set callback

[Kalesh A P <kalesh-anakkur.purayil@broadcom.com>]

From: Damodharam Ammepalli <damodharam.ammepalli@broadcom.com>

Minor cleanup in bnxt_mtu_set_op() to move pre-mature
setting of jumbo flag post mtu check and remove
a redundant mtu set operation from rxq vnic configs.

Fixes: daef48efe5e5 ("net/bnxt: support set MTU")
Cc: stable@dpdk.org
