From 2635a4bdfa8d513c531fa7d7a0ccafc1d6a9ff85 Mon Sep 17 00:00:00 2001 From: Samuel Ortiz Date: Tue, 28 May 2013 15:03:17 +0200 Subject: [PATCH] NFC: llcp: Do not send pending Tx frames when the remote is not ready When we receive a RNR, the remote is busy processing the last received frame. We set a local flag for that, and we should send a SYMM when it is set instead of sending any pending frame.
