scsi: qla2xxx: Add Block Multi Queue functionality.

Tell the SCSI layer how many hardware queues we have based on the number of max queue pairs created. The number of max queue pairs created will depend on number of MSI-X vector count. This feature can be turned on via CONFIG_SCSI_MQ_DEFAULT or passing scsi_mod.use_blk_mq=Y as a parameter to the kernel Reviewed-by: Hannes Reinecke <hare@suse.com> Signed-off-by: Sawan Chandak <sawan.chandak@cavium.com> Signed-off-by: Michael Hernandez <michael.hernandez@cavium.com> Signed-off-by: Himanshu Madhani <himanshu.madhani@cavium.com> Reviewed-by: Christoph Hellwig <hch@lst.de> Signed-off-by: Martin K.

	We decided to get rid of the old Git history and start a new one for several reasons: ) Allow / enforce only high-quality commits (which was not the case for many commits in the history), have a policy that is more close to the one from the Linux kernel. With high quality commits, we mean code that is logically split into commits and commit messages that are signed-off and have a proper subject and message body. We do not allow automatic Github merges anymore, since they are total bullshit. However, we will either cherry-pick your patches or pull them manually. ) The old archive was about ~27MB for no particular good reason. This basically derived from the bad decision that also some PDF files where stored there. From this moment onwards, no binary objects are allowed to be stored in this repository anymore. The old archive is not wiped away from the Internet. You will still be able to find it, e.g. on git.cryptoism.org etc. Signed-off-by: Daniel Borkmann <dborkman@redhat.com> Signed-off-by: Tobias Klauser <tklauser@distanz.ch>
