Subject: [Patch v5 04/18] net/mana: add link update
Date: Fri, 26 Aug 2022 17:34:55 -0700	[thread overview]
Message-ID: <1661560509-11009-5-git-send-email-longli@linuxonhyperv.com> (raw)
In-Reply-To: <1661560509-11009-1-git-send-email-longli@linuxonhyperv.com>

From: Long Li <longli@microsoft.com>

The carrier state is managed by the Azure host. MANA runs as a VF and
always reports "up".
