[dpdk-dev] [PATCH v2] net/bonding: fix lacp negotiation failed

[Liang Zhang]

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.

[dpdk-dev] [PATCH V2] net/bonding: fix lacp negotiation failed

[luyicai]

From: Yicai Lu <luyicai@huawei.com>

When two host is connected directly without any devices like switch,
rx_machine_update would recieving partner lacp negotiation packets,
and partner's port mac is filled with zeros in this packet,
which is different with internal's mode4 mac. So in this situation,
it would never go rx_machine branch and then execute mac swap for negotiation!
Thus bond mode 4 will negotiation failed.
