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.
