It is based on led trigger and class. For our drivers we needed to avoid two things. 1- We receive led trigger on/off on each Rx\Tx frame. In our driver we can not call led command like that. In this driver once driver receive a start of traffic it call the led command to start blinking then we count all bytes of Tx and Rx frame, after two second we count the blink rate of last two second then id blink rate changed we call the led commands 2- Since we can call led command very often, we make sure we call the led command after we receive the statistics notification so we don't need to wake up the ucode id it is in sleep state. This patch was tested with 4965 and 3945. Signed-off-by: Mohamed Abbas Signed-off-by: Ian Schram Signed-off-by: Tomas Winkler Signed-off-by: John W.
