From 749e091ee0065ed366cc26c115abc237e07ed786 Mon Sep 17 00:00:00 2001 From: Abhijeet Kolekar Date: Thu, 21 May 2009 13:44:21 -0700 Subject: iwl3945: improve 3945 leds 'tpt' is a delta throughput (number of packets) and is corelated to brightness of the LED. We already maintain a delta of packets in rxtxpackets. There is no need to calculate this delta again which was affecting the behaviour of LEDS. Also add two new callback functions for ASSOCIATED/DISASSOCIATED states where LED's will be *on* for associated state and *off* for disassociated state.
