brcm80211
brcm80211 is a complete fullmac (BCM4329) and softmac (BCM4313, BCM43224, BCM43225) wireless driver.
Overview
- Completely open source host driver, no binary object files
- On-chip firmware loaded using standard request_firmware()
- Support for BCM43224, BCM43225, BCM4313 (PCIe NIC)
- Framework for supporting new chips, including mac80211-aware embedded chips
- Does not support older PCI/PCIe chips with SSB backplane
- Uses minstrel_ht rate algorithm
- HW based encryption not enabled yet
- Infrastructure for future chips in place.
- AMPDU support
- many software, ucode and phy/radio counters available.
To Be Done once driver is in mainline
- Add support for
- suspend/resume
- RFKill
- 40MHz channels
- powersave
- debufs (for accessing counters and other diagnostic info)
- monitor mode
- IBSS
- AP

The driver is currently available in staging-next branch of the staging tree, available at:
git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging-2.6.git
The driver is also available in the 2.6.38 kernel. When using 'make menuconfig' it can be accessed:
Location: -> Device Drivers
-> Staging drivers
-> Exclude Staging drivers from being built
-> Broadcom IEEE802.11n WLAN drivers
-> Broadcom IEEE802.11n driver style
