Anyone successfully using more than one virtual AP on
3.3 or higher kernels?  It works fine for me on 3.0.32,
but my 3.3.8 and 3.5.7 kernels (and a few similar ones)
all fail with errors like this below:

Hardware is ath9k 3x3 9380 NIC.
Are you using one hostapd instance per vap, or one hostapd instance for
all of them?

One hostapd per VAP.
I had issues with that a long time ago. Use one hostapd instance for all
vaps on the same wiphy, that'll work better.

Well, that would be a lot of user-space churn for me, so I think
I'll try to figure out why it's failing and see if I can fix it.

Thanks,

Well, crap, it looks like it is this commit.  No one considered wanting
to run two hostapd processes on one wiphy :(

    cfg80211: allow registering to beacons

    Add the ability to register to received beacon frames
    to allow implementing OLBC logic in userspace. The
    registration is per wiphy since there's no point in
    receiving the same frame multiple times.
