Subject: [dpdk-dev] [PATCH 3/3] net/virtio: reject unsupported Rx multi queue modes
Date: Tue, 1 Oct 2019 16:44:31 +0100	[thread overview]
Message-ID: <1569944672-24754-3-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1569944672-24754-1-git-send-email-arybchenko@solarflare.com>

From: Dilshod Urazov <Dilshod.Urazov@oktetlabs.ru>

This driver supports none of DCB, RSS or VMDQ modes,
therefore must check and return error if configured incorrectly.

Fixes: c1f86306a026 ("virtio: add new driver")
Cc: stable@dpdk.org
