    Add a '-6' option to the sample pktgen scripts for sending out
    IPv6 packets.

  • b64b0d1e6   pktgen: new pktgen helper functions for samples scripts ... Browse Code »

    Preparing for removing existing samples/pktgen/ scripts, and
    replacing these with easier to use samples.

    This commit provides two helper shell files, that can
    be "included" by shell source'ing. Namely "functions.sh"
    and "parameters.sh".

    The parameters.sh file support easy and consistant parameter
    parsing across the sample scripts. Usage example is printed on
    errors.

    The functions.sh file provides, three new shell functions for
    configuring the different components of pktgen: pg_ctrl(),
    pg_thread() and pg_set(). A slightly improved version of the old
    pgset() function is also provided for backwards compat.

    The new functions correspond to pktgens different components.
    * pg_ctrl() control "pgctrl" (/proc/net/pktgen/pgctrl)
    * pg_thread() control the kernel threads and binding to devices
    * pg_set() control setup of individual devices

    These changes are borrowed from:
