Subject: [dpdk-dev] [PATCH v2 3/5] net/ice: support DCF link status event handling
Date: Thu, 17 Jun 2021 18:17:06 +0800	[thread overview]
Message-ID: <20210617101708.113951-4-ting.xu@intel.com> (raw)
In-Reply-To: <20210617101708.113951-1-ting.xu@intel.com>

When link status changes, DCF will receive virtchnl PF event message.
Add support to handle this event, change link status and update link
info.
