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.

	help
	This option allows you to specify the maximum number of scatter-
	gather entries per I/O. The driver default is 128, which matches
	MAX_PHYS_SEGMENTS in most kernels.  However in SuSE kernels this
	can be 256. However, it may decreased down to 16.  Decreasing this
	parameter will reduce memory requirements on a per controller instance.
