During iSCSI connection terminations, if the target is also terminating at about the same time, the firmware may not complete the driver's request to close or reset the connection. This is fixed by handling other events (instead of the expected completion event) as an indication that the driver's request has been rejected.

When cnic_stop_hw() -> cnic_cm_stop_bnx2x_hw() is called under rtnl_lock() from NETDEV_DOWN event, it waits for cnic_delete_task() to complete. It will deadlock when cnic_delete_task() takes rtnl_lock() before calling cnic_ulp_stop_one(). We fix it by removing the rtnl_lock() in cnic_delete_task(). cnic_ulp_stop_one() has mutex and atomic bit ops to prevent important operations from being done more than once, so it is not necessary to take rtnl_lock().

We service 2 queues (kcq1 and kcq2) in cnic_service_bnx2x_bh(). If the status block index has changed when servicing the kcq2, we must go back and check kcq1.

During cnic shutdown, the original driver code requires userspace to close the uio device within a few seconds. This doesn't always happen as the userapp may be hung or otherwise take a long time to close. The system may crash when this happens. We fix the problem by decoupling the uio structures from the cnic structures during cnic shutdown. We do not unregister the uio device until the cnic driver is unloaded. This eliminates the unreliable wait loop for uio to close. All uio structures are kept in a linked list. If the device is shutdown and later brought back up again, the uio strcture will be found in the linked list and coupled back to the cnic structures.
