sorry for my unclear expression!
The explanation for the trace below is not completely, what I want to say is
when I switches the bonding interface back to l3 mode from l2(first l3->l2 then
l2->l3), the packet can’t be sent to bond-input again.
I have tested the modifications what you mentioned, now it’s able to send the
packet to bond-input again.
