Subject: [dpdk-dev] [PATCH v3 5/7] net/nfp: move VF functions into new file
Date: Thu, 29 Jul 2021 15:47:09 +0200	[thread overview]
Message-ID: <20210729134711.35870-6-heinrich.kuhn@netronome.com> (raw)
In-Reply-To: <20210729134711.35870-1-heinrich.kuhn@netronome.com>

Move any ethdev functionality specific to VF devices into a new file
called nfp_ethdev_vf.c.
