Hey Bruce, Eric, Stephen, sorry about leaving this patchset hanging 
around. Can you apply patches 1-5 & patch 8 in this patch set. I've 
reviewed and acked all of those patches and I believe they are good tof 
go. I need to give further feedback on patches 6 and 7, as I would like 
to avoid bring further rte_ring buffering into the bonded device if 
possible and I think this should be possible but I haven't had time to 
prototype any alternatives but that shouldn't stop the other patches 
being applied.

Thanks
Declan
