From: Abhijeet Kolekar <abhijeet.kolekar@xxxxxxxxx> '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. This fixes http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1771.
