Subject: Re: [PATCH v3] bonding: Inactive slaves should keep inactive
 flag's value

From: Zheng Li <>

> bond_open is not setting the inactive flag correctly for some modes (alb and

> For example, in bond tlb or alb mode, domu send some ARP request which go out

> inactive slave from switch, because the inactive slave's inactive flag is zero,
