We had that discussion offline last week, but let's repeat it here for
the general public.

The most important merge requirement is to not break userspace.  That means
proper support of WE (hopefully via cfg80211), and a single ethX network
device.  The second most important is proper smp support, or good code
quality in general.  We can't afford to merge buggy code.  Third most
important is to make sure it's a full replacment for the current ieee80211
code - for the softmac cards that's mostly trivial, but the half-hard mac
old intel cards are hard.  That's where intel comes into play because you
support that hardware _and_ are pushing for d80211.  That makes your team
pretty much volunteer to fix that up in my eyes.
