Subject: qla2xxx: Reduce mbx-command timeout for Login/Logout requests.
X-Git-Tag: v2.6.39-400.9.0~423^2~96
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=d05e651b63eee96eff1cd1588d0d238d5fe3643f;p=users%2Fjedix%2Flinux-maple.git

qla2xxx: Reduce mbx-command timeout for Login/Logout requests.

Don't use default 30 second mailbox-command timeout for these
serial requests, instead, limit the TMO to the standard 2*RATOV
plus some fudge-factor.

JIRA Key: V2632FC-93
