It's been there for a while..

You shouldn't really need that define for most purposes, but the current
snapshot does indeed include most of the changes from AOSP. The changes
depending on this define will hopefully disappear over time with cleaner
design and new Android releases.

Did you test non-P2P station use?

In theory, yes, but there is only limited testing of this branch with
Galaxy Nexus (or any other specific device/ICS release version in
general). In other words, things may break and not get fixed until
pointed out.. Anyway, my goal is to keep this as a more up-to-date
version of wpa_supplicant for Android than what is available in AOSP.
Though, it should be noted that I'm hoping the need for this to go down
in the future with Android moving closer to the upstream wpa_supplicant,
so that I could stop maintaining this.

Well, I don't think it would be fair to say that any specific branch is
"correct" since this is really a snapshot of wpa_supplicant for the
latest Android release. I happened to be running most of my build tests
with android-4.0.1_r1, but I've moved to a newer snapshot. Then again,
I've also used this wpa_supplicant version built using the ICS toolchain
on Gingerbread, so this is not really supposed to be specific for single
snapshot either. Anyway, not all functionality is expected to be work
and be stable with all combinations one can come up with ;-).
