I created this <hysteria.sk/~neologism/wifi.patch> which could solve problem of
wifi driver not being able to switch among speeds.

I added two files into
sys/net80211/

and change sys/conf/files to
  net80211/ieee80211_proto.c      optional wlan
+ net80211/ieee80211_rssadapt.h   optional wlan
+ net80211/ieee80211_rssadapt.c   optional wlan
  netatalk/aarp.c         optional netatalk

(semi-diff, ie. I added that two files)

and it gives me this message:
"Makefile", line 3104: warning: duplicate script for target
"ieee80211_rssadapt.
ln" ignored
"Makefile", line 3107: warning: duplicate script for target
"ieee80211_rssadapt.
o" ignored

(but it proceeds further) and finally it fails with:
link_elf: symbol ieee80211_rssadapt_raise_rate undefined

simply said - the ieee80211_rssadapt.c didnt get compiled at all (so linker
cannot find the symbol)

By applying the patch and defining wi device you can get the same behaviour

thnx for help
