Hi Fredrik and all,
thanks for your small patch, I will try to use it as fast as I could,
because now a days I don´t have atheros card, but I know how has between my
friends.
Of course I appreciate your work in patch and time you have to spend on it,
but in respect let me one question.
Do you think that it would be only my problem, if one use wireless device
with FreeBSD ?
I think it is problem all users who use atheros cards in 5 GHz band today
and another users who will use FreeBSD in theirs wireless devices like AP,
bridges, AP client and so on.
Dan

Ok, I hacked up a small patch. It's a bit crude since the only interface I
could find to these settings were through sysctl(3).
Put ifath.c in src/sbin/ifconfig and patch src/sbin/ifconfig/Makefile with
the attached patch and re-compile ifconfig.
> ifconfig ath0 distance 1000
> sysctl dev.ath.0.slottime dev.ath.0.acktimeout dev.ath.0.ctstimeout
dev.ath.0.slottime: 13
dev.ath.0.acktimeout: 29
dev.ath.0.ctstimeout: 29
> ifconfig ath0 distance 2500
> sysctl dev.ath.0.slottime dev.ath.0.acktimeout dev.ath.0.ctstimeout
dev.ath.0.slottime: 18
dev.ath.0.acktimeout: 39
dev.ath.0.ctstimeout: 39
