Subject: [dpdk-dev] [PATCH] drivers/net/bonding: fix bug for lacp negotiation failed
Date: Tue, 19 May 2020 19:18:12 +0800 [thread overview]
Message-ID: <1589887092-26360-1-git-send-email-luyicai@huawei.com> (raw)
When two host is connected directly without any devices like switch,
and also enable dedicated tx/rx queues on bonding devices slaves,
rx_machine_update would recieving partner lacp negotiation packets,
which partner's port mac filled with zeros. So in this situation,
it would never go rx_machine branch with correct mac!
Thus bond mode 4 will negotiation failed.
