From: Kalesh AP <kalesh-anakkur.purayil@broadcom.com> The current scheme relies heavily on the RTNL lock for all ULP operations between the L2 and the RoCE driver. Add a new en_dev_lock mutex so that the asynchronous ULP_STOP and ULP_START operations can be serialized with bnxt_register_dev() and bnxt_unregister_dev() calls without relying on the RTNL lock. The next patch will remove the RTNL lock from the ULP_STOP and ULP_START calls.
