Subject: [dpdk-dev] [PATCH 11/27] event/dlb: add flexible PMD to device interfaces
Date: Fri, 26 Jun 2020 23:37:35 -0500
Message-ID: <1593232671-5690-12-git-send-email-timothy.mcdaniel@intel.com> (raw)
In-Reply-To: <1593232671-5690-1-git-send-email-timothy.mcdaniel@intel.com>
From: "McDaniel, Timothy" <timothy.mcdaniel@intel.com>
The PMD uses function pointers so that it can be executed as a bifurcated
PMD accessing hardware via a linux kernel mode driver, or as a PF PMD
where it has complete control of the hardware device.
Note that this interface is not used in the data path.
Signed-off-by: McDaniel, Timothy <timothy.mcdaniel@intel.com>
