From: Hariprasad Kelam <hke...@marvell.com> [ Upstream commit 1ea0166da0509e987caa42c30a6a71f2c6ca1875 ]
Currently in otx2_open on failure of nix_lf_start transmit queues are not stopped which are already started in link_event. Since the tx queues are not stopped network stack still try's to send the packets leading to driver crash while access the device resources.
