iwlwifi: new debugging feature for dumping data traffic
The traffic buffer will only beallocated and used if either bit 23
(IWL_DX_TX) or bit 24 (IWL_DL_RX) of "debug" is set;
example: "debug=0x800000" - log tx data traffic
"debug=0x1000000" - log rx data traffic
"debug=0x1800000" - log both tx and rx traffic
The traffic log will store the beginning portion (64 bytes) of the
latest 256 of tx and rx packets in the round-robbin buffer for
debugging,
user can examine the log through debugfs file.
How to display the current logged tx/rx traffic and txfifo and rxfifo
read/write point:
"cat traffic_log" in /sys/kernel/debug/ieee80211/phy0/iwlagn/debug
directory
By echo "0" to traffic_log file will empty the traffic log buffer and
reset both tx and rx taffic log index to 0.
