>Description:
	pkgsrc/benchmarks/ttcp calculates the line speed wrong.
	When dealing with line speeds, Kbit is 1000, not 1024; Mbit
	is 1000000, not 1048576 etc, but ttcp uses multiples of 1024
	to get the line speed.
>How-To-Repeat:
	Just try ttcp.
>Fix:
	The following patch (to the patched pkgsrc ttcp.c) fixes the bug:
