[SCSI] mpt2sas: Driver will use sas address instead of handle as a lookup
The device driver was not handling updating device handles in all cases across diag resets. To fix this issue, the driver is converted to using sas address instead of handle as a lookup reference to the parent expander or sas_host. Also, for both expanders and sas host, the phy handle will be one unique handle. In the sas host case, the phy handle can be different for every phy, so the change is to set the handle to the handle of the first phy; every phy will be one single sas address(phy 0) instead of a different sas address for every phy(previous implementation). So making one consistent sas address for all the direct attachedports to the sas host, will make it better user experience when using udev /dev/disk/by-path dev nodes Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by: Eric Moore <Eric.moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
