Subject[PATCH AUTOSEL 4.19 142/205] scsi: qla2xxx: Increase abort timeout value
Date
From: Quinn Tran <quinn.tran@cavium.com>

[ Upstream commit 8bccfe0d21b5adbba6ec4fe1776160b80d09f78a ]

Abort IOCB request can take up to 40s or 2 ABTS timeout. We will wait for
ABTS response for 20s. On a timeout, second ABTS can go out with another 20s
timeout. On 2nd ABTS timeout FW will automatically do Logout.
