Improve support for Broadcom wireless devices including the 4300 series.
MidnightBSD 0.3-CURRENT has bwi(4) from DragonFly. It works with a LINKSYS device, but contains a lot of debug code and does not take advantage of some of common code (PHY) in other wifi drivers. Most likely the locking is all wrong and this may die on SMP hardware.
A man page was created based on the DragonFly manual.
- Improve locking, clean up and simplify the code so that it's similar to other devices.
- Clean up and tweak the man page.
- Read up on firmware situation.
