Subject: [PATCH] scsi: target: cxgbit: add support for IEEE_8021QAZ_APP_SEL_STREAM selector
Date: Mon, 01 Jul 2019 16:44:51 +0000	[thread overview]
Message-ID: <1561998771-10265-1-git-send-email-varun@chelsio.com> (raw)

IEEE_8021QAZ_APP_SEL_STREAM is a valid selector
for iSCSI connections, so add code to use
IEEE_8021QAZ_APP_SEL_STREAM selector to get priority
mask.
