Subject: [PATCH 10/14] lpfc: Allow applications to issue Common Set Features mailbox command
Date: Tue, 30 Jun 2020 14:49:57 -0700	[thread overview]
Message-ID: <20200630215001.70793-11-jsmart2021@gmail.com> (raw)
In-Reply-To: <20200630215001.70793-1-jsmart2021@gmail.com>

Currently the driver validates command codes received from the
application. COMMON_SET_FEATURES is not currently being approved.

Add definition of the missing command and allow it to be issued
by applications.
