Subject: [PATCH 02/13] lpfc: Rework sli4 doorbell infrastructure
Date: Fri, 26 Jan 2018 11:31:02 -0800 [thread overview]
Message-ID: <20180126193113.29610-3-jsmart2021@gmail.com> (raw)
In-Reply-To: <20180126193113.29610-1-jsmart2021@gmail.com>
Up until now, all SLI-4 devices had the same doorbells at the same
bar locations. With newer hardware, there are now independent EQ and
CQ doorbells and the bar locations differ.
Prepare the code for new hardwre by separating the eq/cq doorbell into
separate components. The components can be set based on if_type.
