Hi Luca,

I have created patches for those commits from DPDK master branch which
conflicts or caused build errors while merging to 19.11 stable branch.

Please apply them to 19.11 stable branch.

Kalesh AP (3):
  net/bnxt: fix return code handling in VLAN config
  net/bnxt: handle HW filter setting when port is stopped
  net/bnxt: remove a redundant variable

[ 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().

[ upstream commit 90c957ef3b11f361dd8e6519d9e195f01295b23e ]

Use "dev->data->dev_started" state, instead of local "dev_stopped"
to check whether port has been started or not.
