++ * 
++ * ChangeLog
++ *	19.02.2002: Gianni Tedesco <gianni@ecsc.co.uk>
++ *		Fixed SMP re-entrancy problem using per-cpu data areas
++ *		for the skip/shift tables.
++ *	02.05.2001: Gianni Tedesco <gianni@ecsc.co.uk>
++ *		Fixed kernel panic, due to overrunning boyer moore string
++ *		tables. Also slightly tweaked heuristic for deciding what
++ * 		search algo to use.
++ * 	27.01.2001: Gianni Tedesco <gianni@ecsc.co.uk>
++ * 		Implemented Boyer Moore Sublinear search algorithm
++ * 		alongside the existing linear search based on memcmp().
++ * 		Also a quick check to decide which method to use on a per
++ * 		packet basis.
