[SCSI] mpt2sas: Modify code to support Expander switch
Issue : Switch swap doesn't work when device missing delay is enabled. (1) add support to individually add and remove phys to and from existing ports. This replaces the routine _transport_delete_duplicate_port. (2) _scsih_sas_host_refresh - was modified to change the link rate from zero to 1.5 GB rate when the firmware reports there is an attached device with zero link. (3) add new function mpt2sas_device_remove, this is wrapper function deletes some redundant code through out driver by combining into one subrountine (4) two subroutines were modified so the sas_device, raid_device, and port lists are traversed once when objects are deleted from the list. Previously it was looping back each time an object was deleted from the list. Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
