Subject: [PATCH] prism54: update to WE-19 for WPA support

Add WE-19 capabilities to prism54 fullmac driver so that it supports the
necessary Wireless Extensions WPA calls.  Convert reporting of WPA/RSN
Generic Information Elements to IWEVGENIE rather than pre-WE-19
IWEVCUSTOM as well.

Subject: [PATCH] ieee80211: small ERP handling additions

This adds a flag to the ieee80211_network structure which indicates whether
the stored erp_value is valid (a check against 0 is not enough, since an ERP
of 0 is valid and very meaningful).

I also added the ERP IE bit-definitions to ieee80211.h.

This is needed by some upcoming softmac patches.

Subject: [PATCH] softmac: ERP handling and driver-level notifications

This patch implements ERP handling in softmac so that the drivers can support
protection and preambles properly.

I added a new struct, ieee80211softmac_bss_info, which is used for
BSS-dependent variables like these.

A new hook has been added (bssinfo_change), which allows the drivers to be
notified when anything in bssinfo changes.

I modified the txrates_change API to match the bssinfo_change API. The
existing one is a little messy and the usefulness of providing the old rates
is questionable (and can be implemented at driver level if really necessary).
No drivers are using this API (yet), so this should be safe.

Subject: [PATCH] ieee80211: Make ieee80211_rx_any usable

ieee80211_rx_any is new to 2.6.18-rc1, even though it appears this function
was never completed:

http://lists.sipsolutions.net/pipermail/softmac-dev/2006-February/000103.html

This patch changes ieee80211_rx_any to always claim the skb, which avoids
further driver complexity and the possibility of leaking management frames.
It also exports the function so that people can actually use it.
