For as far as I understand, the regression was introduced by Jiri's patches that are not yet 
accepted in net-next-2.6, so this path definitely need the full patch series to be applied before. 
And there is no special urgency to fix this regression, because it doesn't "exist" yet anywhere 
except in some sandboxes.

This patch change the reinjection to inject at the slave level instead of the master level, because 
in Jiri's patch series, ARP handling moved from a normal protocol handler registered at the master 
level to the rx_handler at the slave level.

Jiri, do I miss something ?

I agree with your concerns, and this is the reason why Jiri and I are working hard to try and fight 
every possible problems in the whole package of patch. I think that, at the end, Jiri and I will 
have to properly resubmit the whole thing, for the convenient of those who will have to decide to 
accept it or not.
