what does 0 mean? the wiki says: 0 meters away, so a short
ack-timeout is used, or is '0' something special, eg. driver default?

i tested a p2p/longshot here, where both stations are 350m away, but
invoking on both sides:

iw phy phy0 set distance 350

shows, that the link gets really worse, also with 500 or 2000.
can't it be changed during runtime?
