Subject: [RFC PATCH 0/2] rx zero copy interface for af_packet
Date: Fri, 27 Jan 2017 13:33:20 -0800	[thread overview]
Message-ID: <20170127213132.14162.82951.stgit@john-Precision-Tower-5810> (raw)

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
