Oh, that's right, I think I've been testing SVN trunk with this patch
applied (maybe with =| MONITOR hunk, which I found in another version of
similar patch).  Without a patch injection test fails immediately,
before wi_write() gets a chance to trigger.

I've seen people say this, but I could not find more elaborative answer.
I am also not sure about AHDEMO mode, since iwi(4) reports this for me:

$ ifconfig iwi0 list caps
iwi0=25818300<IBSS,PMGT,SHPREAMBLE,MONITOR,WPA1,WPA2,WME,BGSCAN>
