Subject: Add rtl8180 wireless driver

This patch adds a mac80211 based wireless driver for the rtl8180 and
rtl8185 PCI wireless cards.  Also included are some rtl8187 changes
required due to the relationship between that driver and this one.

Michael Wu is primarily responsible for the initial driver and rtl8185
support.  Andreas Merello provided the additional rtl8180 support.

Thanks to Jukka Ruohonen for the donating a rtl8185 card! It was very
helpful for the rtl8225z2 code.

The Signed-off-by information below is collected from the individual
patches submitted to wireless-2.6 before merging this driver upstream.

From 32bfd35d4b63bd63de4bb0d791ef049c3c868726 Mon Sep 17 00:00:00 2001

Subject: mac80211: dont use interface indices in drivers

This patch gets rid of the if_id stuff where possible in favour of
a new per-virtual-interface structure "struct ieee80211_vif". This
structure is located at the end of the per-interface structure and
contains a variable length driver-use data area.

This has two advantages:
 * removes the need to look up interfaces by if_id, this is better
   for working with network namespaces and performance
 * allows drivers to store and retrieve per-interface data without
   having to allocate own lists/hash tables
