Hi Eduardo,
I'm using this:
#!/bin/bash
mount -t debugfs nodev /sys/kernel/debug
echo "Prep for tx99"
iw phy phy0 interface add moni0 type monitor
ip link set dev moni0 up
echo "Activating tx99"
echo 15 > /sys/kernel/debug/ieee80211/phy0/ath9k/tx99_power
echo 1 > /sys/kernel/debug/ieee80211/phy0/ath9k/tx99
Is that not enough?
Ifconfig lists moni0 as follows:
moni0 Link encap:UNSPEC HWaddr
BC-30-7E-BC-59-98-35-65-00-00-00-00-00-00-00-00
