Re: [PATCHv3 net 0/2] bonding: fix incorrect mac address setting

[Hangbin Liu <liuhangbin@gmail.com>]

Please hold on this patch. Our QE reported that with bare NIC, the
backup NIC can't receive the NS messages even after joining the multicast
MAC group. But after remove the backup NIC from bond, the NIC interface
could receive the NS message.

This is weird, it looks the backup NIC dropped the NS message somewhere,
even using tcpdump (the NIC will be in promisc mode) I can't capture the
NS message on backup slave.

I need to debug more.

Thanks
