Hi,

2014-10-01 13:57, mukawa@igel.co.jp:
> 'null PMD' is a driver of the virtual device particulary designed to measure
> performance of DPDK PMDs. When an application call rx, null PMD just allocates
> mbufs and returns those. Also tx, the PMD just frees mbufs.
> 
> The PMD has following options.
> - size: specify packe size allocated by RX. Default packet size is 64.
> - copy: specify 1 or 0 to enable or disable copy while RX and TX.
> 	Default value is 0(disbaled).
> 	This option is used for emulating more realistic data transfer.
> 	Copy size is equal to packet size.
> 
> To use the PMD, enable CONFIG_RTE_BUILD_SHARED_LIB in config file. Then
