From: Jay Cliburn @ 2007-07-15 16:03 UTC (permalink / raw)
To: jeff; +Cc: jacliburn, csnook, atl1-devel, netdev, linux-kernel
Reorder functions in atl1_main into more logical groupings to make the
code easier to follow. This patch is large, but it's harmless; it neither
adds nor removes any functionality whatsoever.
