Subject: qla2xxx: Set relogin flag when we fail to queue login requests.
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=080c9517eaa84a2edf70382d60c46c3452869bf2;p=linux-beck.git

qla2xxx: Set relogin flag when we fail to queue login requests.

If we fail to queue an srb for an async login we should set the
relogin flag so it will be retried as the reason for the queuing
failure was most likely transient.  Failure to do this can lead to
failed paths as login is never retried if the relogin flag is not
set.
