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

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.

This fixes Bug #9414 for b43legacy. This patch is the equivalent of one
submitted earlier for b43.
Since addition of the rfkill callback, the LED associated with the off
switch on the radio has not worked for several reasons:
(1) Essential data in the rfkill structure were missing.
(2) The rfkill structure was initialized after the LED initialization.
(3) There was a minor memory leak if the radio LED structure was inited.
Once the above problems were fixed, additional difficulties were noted:
(4) The radio LED was in the wrong state at startup.
(5) The radio switch had to be manipulated twice for each state change.
(6) A circular mutex locking situation existed.
(7) If rfkill-input is built as a module, it is not automatically loaded.
This patch fixes all of the above and removes a couple of sparse warnings.
