Ok, in my case, they were selecting based on BSSID, though it didn't work with
using 'any' either.  It very well may have worked with your patch, but I have
no way to test that now.  For my particular use, I'll just always set bss_max_count
high.  As long as you think it will work for normal-ish
users that are just using standard OS configs and tools then I think everything
will be fine.
