Subject: [question] bond_set_slave_inactive_flags

Jay,

Looking at function bond_set_slave_inactive_flags:

static inline void bond_set_slave_inactive_flags(struct slave *slave)
{
        struct bonding *bond = netdev_priv(slave->dev->master);
        if (!bond_is_lb(bond))
                slave->state = BOND_STATE_BACKUP;
        if (!bond->params.all_slaves_active)
                slave->dev->priv_flags |= IFF_SLAVE_INACTIVE;
        if (slave_do_arp_validate(bond, slave))
                slave->dev->priv_flags |= IFF_SLAVE_NEEDARP;
}

Why BOND_STATE_BACKUP is set only for non-lb bonds?
This was introduced by 8f903c708fcc2b579ebf16542bf6109bad593a1d but
I do not see why.

Thanks for reply in advance.

Jirka
