From eae38eede2e5f70d65f09327297bd698b0d3ea7e Mon Sep 17 00:00:00 2001 From: Marcel Holtmann Date: Mon, 5 Oct 2009 12:23:48 +0200 Subject: Bluetooth: Add RFCOMM option to use L2CAP ERTM mode By default the RFCOMM layer would still use L2CAP basic mode. For testing purposes this option enables RFCOMM to select enhanced retransmission mode.
