Bluetooth: Increment unacked_frames count only the first transmit
Suraj Sumangala [Wed, 9 Mar 2011 09:14:05 +0000 (14:14 +0530)]
This patch lets 'l2cap_pinfo.unacked_frames' be incremented only
the first time a frame is transmitted.

Previously it was being incremented for retransmitted packets
too resulting the value to cross the transmit window size.
