Thank you for the pointer, I am looking at the patch ad
see if it help. In my case, that will do the trick, but as mentioned
by Dave it may not have its place in a general distro.
Perso I would rather "cloning" <-- do not flame me, it is not my intent to
open a long thread :-)
the skb received on the bond and pass the clone + original skb
to the tap. This gives a "symetrical" behavior to the tap...
Some of the point made for LLDP etc... may not require this
patch if one adds the processing as a protocol.
Thank you.

PJ Waskiewicz posted a patch that introduced a new socket option for
PF_PACKET sockets to return the orig_dev->ifindex instead of
dev->ifindex in sockaddr_ll. He posted the patch on March 8th.

He also re-posted it on March 19th, at which point you (Dave) told him
that it was in your backlog and he didn't need to keep resending it.
To me it's seem like a decent opt-in solution for applications that
might care, without changing existing behavior. Laurent, would that
change help you? Dave, is there a reason you can see why this
wouldn't work?
