Subject: [dpdk-dev] [PATCH v2 15/19] xmvnet3: move vmxnet3 PMD to drivers/net
Date: Fri, 15 May 2015 16:56:59 +0100 [thread overview]
Message-ID: <1431705423-16134-16-git-send-email-bruce.richardson@intel.com> (raw)
In-Reply-To: <1431705423-16134-1-git-send-email-bruce.richardson@intel.com>
Move vmxnet3 PMD to drivers/net directory.
As part of the move, rename the "vmxnet3" subdirectory, containing the
original FreeBSD drivers, from "vmxnet3" to the more standard name
"base", to indicate it contains the base drivers used for the
implementation.
