You forgot one bond_dev->dev_addr[5] occurrence here

Could you check if bond->xmit_hash_policy(skb, bond_dev, bond->slave_cnt);
could be replaced by bond->xmit_hash_policy(skb, bond->slave_cnt),
now that various implementations dont need bond_dev anymore ?

static int bond_xmit_hash_policy_l23(struct sk_buff *skb, int count) ...

Dont forget your "Signed-off-by: Jasper Spaans <spaans@...-it.com>",
