I've just started to look around for WPS support and I've found the
same - the code is gone.

Althought several Intel-based versions were mentioned (Atheros, Metalink,
Marvell, Sony/Saice), I was able to find just the one from Saice (the
w1.fi/contrib/ dir was a victim of the disk crash I suppose).

I can see in hostap-historic.git that some code by Jouni was present
(and it doesn't look like being based on Intel code, but I didn't spend
too much time checking). In this tree, the wpa_supplicant part was removed
(Jan-26), the hostap part was kept. As already mentioned, both parts
were lost in current 0.6.3-based hostap.git.

As this has happened already some time ago, is there anything new
concerning this issue?

I will most probably have some time to dig into this (mainly enrollee-part,
running on top of wireless-testing mac80211 tree) so I'd like to know what
the current status is, as the list/google is quiet on this topic.

(I didn't try the code in hostap-historic.git (prior to removal of
wpa_supplicant part) yet since I don't have WPS-enabled AP on hand, but
that's fixable..)
