Subject: [dpdk-dev] [PATCH v3 1/2] bonding: fix lacp negotiation failed
Date: Fri, 15 Mar 2019 16:53:38 +0800	[thread overview]
Message-ID: <1552640019-16619-1-git-send-email-zhangliang@bigo.sg> (raw)
Message-ID: <20190315085338.To-5oMknOq4hCl-DgsDdd8fis_q6NwSwaHsdzk-YVMk@z> (raw)
In-Reply-To: <1552566441-14658-1-git-send-email-zhangliang@bigo.sg>

When monitor(port-mirroring) traffic from other lacp port-channel,
rx_machine_update may recieving other lacp negotiation packets.
Thus bond mode 4 will negotiation failed.
