Use standards defined 2 * RA_TOV as a timeout for ELS Request retries. And standards defined 3 * RA_TOV as a timeout for FC-CT Request retries. Also, added a check to send RPSC2 to a Brocade Fabric only. Signed-off-by: Jing Huang <huangj@brocade.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
