Subject: [PATCH 1/2] qla2xxx: Initialized mailbox to prevent driver load failure
Date: Tue, 22 Oct 2019 12:36:42 -0700 [thread overview]
Message-ID: <20191022193643.7076-2-hmadhani@marvell.com> (raw)
In-Reply-To: <20191022193643.7076-1-hmadhani@marvell.com>
This patch fixes issue with Gen7 adapter in a blade enviornment,
where one of the port will not be detected by driver. Firmware
expectes mailbox 11 to be set or clear by driver for newer ISP.
