Subject: [dpdk-dev] [PATCH 06/22] event/dlb2: add probe
Date: Fri, 11 Sep 2020 15:26:11 -0500 [thread overview]
Message-ID: <1599855987-25976-7-git-send-email-timothy.mcdaniel@intel.com> (raw)
In-Reply-To: <1599855987-25976-1-git-send-email-timothy.mcdaniel@intel.com>
The DLB2 hardware is a PCI device. This commit adds
support for probe and other initialization. The
dlb2_iface.[ch] files implement a flexible interface
that supports both the PF PMD and the bifurcated PMD.
The bifurcated PMD will be released in a future
patch set. Note that the flexible interface is only
used for configuration, and is not used in the data
path. The shared code is added in pf/base.
