Message-Id: <1242061906-16226-1-git-send-email-markmc@redhat.com> Date: Mon, 11 May 2009 18:11:44 +0100 From: Mark McLoughlin <markmc@...hat.com> To: Rusty Russell <rusty@...tcorp.com.au> Cc: netdev@...r.kernel.org, Dor Laor <dor@...hat.com>, Avi Kivity <avi@...hat.com>, virtualization@...ts.linux-foundation.org, Mark McLoughlin <markmc@...hat.com> Subject: [PATCH 1/3] virtio: teach virtio_has_feature() about transport features Drivers don't add transport features to their table, so we shouldn't check these with virtio_check_driver_offered_feature(). We could perhaps add an ->offered_feature() virtio_config_op, but that perhaps that would be overkill for a consitency check like this.
