Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	  b43legacy is a driver for 802.11b devices from Broadcom (BCM4301 and
	  BCM4303) and early model 802.11g chips (BCM4306 Ver. 2) used in the
	  Linksys WPC54G V1 PCMCIA devices.

	  Newer 802.11g and 802.11a devices need b43.

	  It is safe to include both b43 and b43legacy as the underlying glue
	  layer will automatically load the correct version for your device.

	  This driver uses V3 firmware, which must be installed separately using
	  b43-fwcutter.

	  This driver can be built as a module (recommended) that will be
	  called "b43legacy". If unsure, say M.
