From 43d28b6515a6ea580a198df3e253e88236f08978 Mon Sep 17 00:00:00 2001 From: Daniel Turull Date: Wed, 9 Jun 2010 22:49:57 +0000 Subject: pktgen: increasing transmission granularity This patch increases the granularity of the rate generated by pktgen. The previous version of pktgen uses micro seconds (udelay) resolution when it was delayed causing gaps in the rates. It is changed to nanosecond (ndelay). Now any rate is possible. Also it allows to set, the desired rate in Mb/s or packets per second. The documentation has been updated. Signed-off-by: Daniel Turull Signed-off-by: Robert Olsson Signed-off-by: David S.
