[dpdk-stable] [PATCH 19.11 2/3] net/bnxt: handle HW filter setting when port is stopped

[Kalesh A P]

From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

[ upstream commit 1c25103326f9e94c9adade33da09ac772a1e59a2 ]

Driver destroy the VNIC when the port is brought down.
Port HW filter setting such as promiscuos, allmulti and
VLAN filtering will be applied when port is started.

Fixed to return success silently for these callbacks
when port is stopped. Also fixed to clear "bp->dev_stopped"
before invoking bnxt_vlan_offload_set_op() in bnxt_dev_start_op().
