Officially AFAIK no

AFAIK no, there's no port of YAFFS or JFFS/JFFS2 for NetBSD

AFAIK Wasabi Systems people (http://www.wasabisystems.com) have some NAND (or 
NOR ? I don't remember..) Flash implementation plus journaled FS for NetBSD 
but it isn't available for public domain. You probably should ask them 
directly :)

Take a look at Linux MTD project at http://www.linux-mtd.infradead.org. They 
have done a lot of work and, theoretically, it can be ported/rewritten for 
NetBSD. Though from my personal exp this 1) needs a lot of work 2) Linux MTD 
is poorly documented.

Atheros Driver, changing ACK timeout?

Is there a way to change the ACK timeout for the atheros driver? 

I want to do some long distance links ( eg, 30km + ) and the default ACK 
timeout is not long enough for the RF to get there and back. As a result, 
DUP packets occur when pinging, and in general performance is horrid. 

Ive looked thru the ath driver stuff, and I could not see anything relating 
to changing the ACK timeout.. perhaps it is in the HAL? 

Any ideas? I dont want to use staros or such like ( which can alter the ACK 
timeout ) 

Thanks 

P.S Oranges and Apples and Pinapples and such fruit tastes good.

Like many things, this is indeed buried in the HAL, which we don't really have 
access to.

How are you propagating the signal 30km?
