Subject: net/bnxt: fix VLAN add when port is stopped
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=8b60154d4b8a413eec43aafce1b4341dd575d4c3

net/bnxt: fix VLAN add when port is stopped

Driver destroys the vnic when the port is brought down.
When user tries to add a vlan when port is stopped, driver
issues HWRM command to FW with invalid vnic_id and it fails.

Fixed to return an error while setting vlan when port is
not started.
