From 56af2568c27ee697a5a34cf037e3253e7b77e80b Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Wed, 30 May 2012 18:06:11 +0200 Subject: [PATCH] NFC: Send a receiver ready frame only to reply to an I frame Sending an RR as a reply to another RR is fine but not quite logical. We should send RRs only as a reply to I frames.
