3357  * The ThunderBolt HW has an option for the driver to directly
3358  * access the underlying disks and operate on the RAID.  To
3359  * do this there needs to be a capability to keep the RAID controller
3360  * and driver in sync.  The FreeBSD driver does not take advantage
3361  * of this feature since it adds a lot of complexity and slows down
3362  * performance.  Performance is gained by using the controller's
3363  * cache etc.
3364  *
3365  * Even though this driver doesn't access the disks directly, an
3366  * AEN like command is used to inform the RAID firmware to "sync"
3367  * with all LD's via the MFI_DCMD_LD_MAP_GET_INFO command.  This
3368  * command in write mode will return when the RAID firmware has
3369  * detected a change to the RAID state.  Examples of this type
3370  * of change are removing a disk.  Once the command returns then
3371  * the driver needs to acknowledge this and "sync" all LD's again.
3372  * This repeats until we shutdown.  Then we need to cancel this
3373  * pending command.
3374  *
3375  * If this is not done right the RAID firmware will not remove a
3376  * pulled drive and the RAID won't go degraded etc.  Effectively,
3377  * stopping any RAID mangement to functions.
3378  *
3379  * Doing another LD sync, requires the use of an event since the
3380  * driver needs to do a mfi_wait_command and can't do that in an
3381  * interrupt thread.
3382  *
3383  * The driver could get the RAID state via the MFI_DCMD_LD_MAP_GET_INFO
3384  * That requires a bunch of structure and it is simpler to just do
3385  * the MFI_DCMD_LD_GET_LIST versus walking the RAID map.
