    cfg80211: introduce nl80211 testmode command · aff89a9b
    Johannes Berg authored
    This introduces a new NL80211_CMD_TESTMODE for testing
    and calibration use with nl80211. There's no multiplexing
    like like iwpriv had, and the command is not available by
    default, it needs to be explicitly enabled in Kconfig and
    shouldn't be enabled in most kernels.
    The command requires a wiphy index or interface index to
    identify the device to operate on, and the new TESTDATA
    attribute. There also is API for sending replies to the
    command, and testmode multicast messages (on a testmode
    multicast group).
    I've also updated mac80211 to be able to pass through the
    command to the driver, since it itself doesn't implement
    the testmode command.
    Additionally, to give people an idea of how to use the
    command, I've added a little code to hwsim that makes use
    of the new command to set the powersave mode, this is
    currently done via debugfs and should remain there, and
    the testmode command only serves as an example of how to
    use this best -- with nested netlink attributes in the
    TESTDATA attribute. A hwsim testmode tool can be found at
    . This tool is BSD
    licensed so people can easily use it as a basis for their
    own internal fabrication and validation tools.
