Subject: [dpdk-dev] [RFC PATCH 07/17] virtio: Remove unnecessary adapter structure
Date: Mon, 8 Dec 2014 14:21:46 +0800 [thread overview]
Message-ID: <1418019716-4962-8-git-send-email-changchun.ouyang@intel.com> (raw)
In-Reply-To: <1418019716-4962-1-git-send-email-changchun.ouyang@intel.com>
Cleanup virtio code by eliminating unnecessary nesting of
virtio hardware structure inside adapter structure.
Also allows removing unneeded macro, making code clearer.
