Subject: [Patch v6 02/18] net/mana: add device configuration and stop
Date: Tue, 30 Aug 2022 15:51:35 -0700	[thread overview]
Message-ID: <1661899911-13086-3-git-send-email-longli@linuxonhyperv.com> (raw)
In-Reply-To: <1661899911-13086-1-git-send-email-longli@linuxonhyperv.com>

From: Long Li <longli@microsoft.com>

functions to allocate device queues. This patch adds the code for device
configuration and stop.
