staging: brcm80211: revised README

Removed duplicated text sections in README. Removed Bugs/problems that no longer
occur. One brcmsmac instability remains, (to be solved with new ucode), that has
been moved to the TODO file.

drivers/staging/brcm80211/README

-Broadcom Mac80211 driver
+Broadcom brcmsmac (mac80211-based softmac PCIe) and brcmfmac (SDIO) drivers.
 
-Firmware installation
+Completely open source host drivers, no binary object files.
+
+Support for the following chips:
+===============================
+
+    brcmsmac (PCIe)
+    Name        Device ID
+    BCM4313     0x4727
+    BCM43224    0x4353
+    BCM43225    0x4357
+
+    brcmfmac (SDIO)
+    Name
+    BCM4329
+
+Both brcmsmac and brcmfmac drivers require firmware files that need to be
+separately downloaded.

+Broadcom brcmsmac driver
+===============================================================
+- Support for both 32 and 64 bit Linux kernels
 
-Bugs/Problems
-==============
-- Driver can get confused while scanning during high throughput, can cause
-  burping, hanging, and possible crashing.
-- Occasional hangs & burps with BCM43224 on 2.4 GHz with dual stream rates.
-- Occasional crashes with BCM43224 on multicore machines.
 
+Firmware installation

-Broadcom fullmac driver
-
-This is production driver.
 
-What's here
-===========
-- Completely open source host driver, no binary object files
-- Features Broadcom's OneDriver architecture (single source base for
-  supported chips and architectures)
-- On-chip firmware loaded using standard request_firmware()
-- Support for BCM4329(SDIO)
+===============================================================
+Broadcom brcmfmac driver
+===============================================================
+- Support for 32 bit Linux kernel, 64 bit untested
 
-What's done
-==========
-- Integration with cfg80211 stack
-- Most of Mac functionality is performed in dongle
-- A-MPDU single stream rates
-- BCM4329:	Dualband, Single stream, 20MHz channels
