Update: turns out building w/ wpa_supplicant and hostapd as separate
packages (instead of wpad which combines them into one binary) solves
the problem. A newer version of wpad/hostapd/wpa_supplicant is available
since we pinned AA to revisions from April, so Will and Jordan
experimented with using the new version.

I just built with OpenWRT pinned @36682 and the packages feed @36537,
and can confirm it fixes the problem, while including the newer version
of wpad/hostapd/wpa_supplicant. IBSS-RSN works as well.

Thanks Will and Jordan for doing a lot of hard work investigating this
today!
