A bit too little investigation, it seems.  The rtl8180 driver doesn't
get lots of attention, but it has been hit several times since 2007.
As for master and ad-hoc modes, I've recently taken interest there
and expect to be adding patches shortly.

No it will not.  For one, svn indicates rtl-wifi is nowhere near as
active as you indicate:

	[linville-t400.local]:> svn log
	r83 | falmouth | 2008-07-09 08:52:33 -0400 (Wed, 09 Jul 2008) | 1 line

	our CCMP, TKIP and WEP modules names end in -rtl

Beyond that, no one from there is posting any patches and in any case
it is rather rare to simply drop one more-or-less working driver in
favor of another one simply because it appears from nowhere.

Anyway, as I indicated I have been taking more interest in rtl8180
lately and I expect it to be greatly improved at least in time for
2.6.35 (since the 2.6.34 development cycle will be ending soon).
