Ugh. :-) Yeah, that whole binary ABI change thing sucks.

Yeah, drivers should be including opt_wlan.h. I had a chat with warner
about this years ago and IIRC the thought was that we shouldn't have
/binary ABI/ changes because of opt_XXX.h flags that aren't global.. but I
don't know how many people care about things at that level now?
