Subject: [RFC PATCH 0/2] rx zero copy interface for af_packet

This is an experimental implementation of rx zero copy for af_packet.
Its a bit rough and likely has errors but the plan is to clean it up
over the next few months.

And seeing I said I would post it in another thread a few days back
here it is.

Comments welcome and use at your own risk.

Thanks,
John
