Anirban Chakraborty 2afa19a937 [SCSI] qla2xxx: Add QoS support. 
Set the number of request queues to the module paramater
ql2xmaxqueues.  Each vport gets a request queue. The QoS value
set to the request queues determines priority control for queued
IOs. If QoS value is not specified, the vports use the default
queue 0.
