When the hba port gets logged out of the fabric, or other such transitional state when the physical link is still present, the driver doesn't receive a loop up asyn event (where the link data rate currently gets set). Hence send a explicit mailbox command to get the link rate in such conditions.

Some of our virtual SCSI hosts don't have a proper bus parent at the top, which can be a problem for doing DMA on them This patch makes the host device cache a pointer to the physical bus device and provides an extra API for setting it (the normal API picks it up from the parent). This patch also modifies the qla2xxx and lpfc vport logic to use the new DMA host setting API.

This patch modifies scsi_host_template->change_queue_depth so that it takes an argument indicating why it is being called. This will be used so that if a LLD needs to do some extra processing when handling queue fulls or later ramp ups, it can do so. This is a simple port of the drivers setting a change_queue_depth callback. In the patch I just have these LLDs adjust the queue depth if the user was requesting it.

The interrupt handler clears the interrupt status register for response updates in the base queue while working in the multique mode. This could lead to missing interrupt for async events, mail box completions etc. as these are also handled in the base queue.
