[zd1211-devs] Please merge the Remco patch

[Steven F. <sf...@io...>]

After applying Remco's patch to version r48 of the driver, I like him
was able to get kismet to operate with zd1211.

During this time I had a few correspondences with Mike Kershaw (the
programmer of Kismet) in IRC. According to him he received some early
data dumps with malformed packets. This packets made it hard to write
a Kismet <==> zd1211 interface. What Mike said about the malformed
packets seamed to me to correspond with what Remco said in his letter
of 2005-12-27.

I later informed Mike Kershaw that I was able to get Kismet to operate
with zd1211 when I applied a patch. Mike said that he would be
interested in updating Kismet after the patch was part of the mainline
driver.

I would like to see Kismet and working with zd1211, so I would be
grateful if the patch was merged into the mainline of zd1211 driver
development.

I did have two problems that occurred while using r48+Remco_patch and
the hostap interface.  One problem was that signal strength. According
to Kismet the signal strength was ether not reported or when it was
reported it was always the exact same combination of numbers. The way
I see it, this problem could be caused by zd1211 not reporting it's
signal strength when in monitor mode. On the other hand zd1211 could
have been reporting signal strength but Kismet did not find the
information. This makes sense because the interface between Kismet and
zd1211 was not specifically written for zd1211 but was written for
hostap.

The second problem I had was that the after 2 to 5 minutes of
operating Kismet would shutdown because in its own words "the
interface was no longer available". Mike Kershaw said this was usually
caused be the operation of a DHCP daemon or "pump" but it could be
caused be a bug in the driver. Nether of those programs appeared to be
operation in my computer.

Thanks for your consideration.
