IMHO, the original patch was absolutely evil hack touching multiple
layers, for the sake of a very special problem.
I think, that in order to kick forwarding table on switches, lagg
- allocate an mbuf itself
- set its source hardware address to its own
- set destination hardware to broadcast
- put some payload in there, to make packet of valid size. Why should it be
gratuitous ARP? A machine can be running IPv6 only, or may even use whatever
higher level protocol, e.g. PPPoE. We shouldn't involve IP into this Layer 2
problem at all.
- Finally, send the prepared mbuf down the lagg member(s).
And please don't hack half of the network stack to achieve that :)
Totus tuus, Glebius.
