The SCSI midlayer stops all command processing when in error handling, which means there is no chance for command reuse when the abort handler is called.

The isd200 sub-driver increments the command serial number despite not using it at all in it's routine for sending internal scsi commands.

Currently fcoe interface cleanup is done after ndo_fcoe_disable and that prevents logoff going out to the peer, so this patch moves all netdev cleanup and its releasing inside fcoe_interface_cleanup to have log off before ndo_fcoe_disable disables the fcoe. This patch also fixes asymmetric rtnl locking around fcoe_if_destroy, as currently this function requires rtnl held by its caller and then have this func drops the lock, instead now don't have any processing under rtnl inside fcoe_if_destroy, this required moving few func to get build working again.

Added REC_TOV_CONST intent was to have rec tov as e_d_tov + 1s but currently it is e_d_tov + 1ms since e_d_tov is stored in ms unit. Also returned rec tov by get_fsp_rec_tov is in ms and this ms tov is used as-is with fc_fcp_timer_set expecting jiffies tov. Fixed this by having get_fsp_rec_tov return rec tov in jiffies as e_d_tov + 1s and then use jiffies tov w/ fc_fcp_timer_set. Also some cleanup, no need to cache get_fsp_rec_tov return value in local rec_tov at various places.

When rmmoving the underlying fcoe transport driver module by force when it's attached and in use, the correspoding netdev mapping should be cleaned up properly as well, otherwise the lookup for a given netdev for the transport would still return non NULL pointer, causing "unable to handle paging request" bug.

The host_lock is still used to protect the can_queue value in the Scsi_Host, but it doesn't need to be held and released by each caller. This patch moves the lock usage into the fc_fcp_can_queue_ramp_up and fc_fcp_can_queue_ramp_down routines.

The check of module state being MODULE_STATE_LIVE is no longer needed for the individual fcoe transport driver, e.g., fcoe.ko, as sysfs entries now go to libfcoe now, if it reaches fcoe.ko, it has to be already registered. The module state check for libfcoe will guard the possible race condition of sysfs being writable before module_init function is called and after module_exit.

These checks were initially added to avoid a lockdep false positive when dealing with the s_active, rtnl and fcoe_config_mutex mutexes. Recently the create, destroy, enable and disable sysfs entries were moved from fcoe.ko to libfcoe.ko. With this change the mutex usage was shuffled around and the lockdep false positive stopped happening. We can now remove these checks.

This code was incorrectly ported from fcoe.c when the fcoe transport infrastructure was put into place. It was originally needed in fcoe.c when dealing with the rtnl mutex. In that code it was only needed to avoid a lockdep false positive. In libfcoe we don't deal with the rtnl mutex, we don't get the lockdep false positive and therefore we don't need these checks.

Before driver's own internal state is marked as PLOGI/PRLI complete. This additional check closes a window seen with dual-personality initiator/target devices where a driver's PLOGI/PRLI request occurs within the window after the target's PLOGI request has completed, but prior to the target's PRLI arriving and processed by the firmware. Without this additional check, the firmware will return port-information stating that the port neither supports target nor initiator functions, causing the driver to register the rport prematurely to the FC-transport without the proper 'roles' being set.

[SCSI] qla2xxx: Include request queue ID in the upper 16-bits of the I/O handle for Abort I/O IOCBs. The upper 16-bits of the handle for all I/O in multi-queue supported drivers carries the ID of the request queue it was submitted on. When using Abort I/O IOCB, the driver needs to also populate the upper 16-bits in the handle_to_abort field so the fw can correlate with the actual I/O.
