    firewire: cdev: add PHY pinging · cc550216
    Stefan Richter authored
    This extends the FW_CDEV_IOC_SEND_PHY_PACKET ioctl() for /dev/fw* to be
    useful for ping time measurements.  One application for it would be gap
    count optimization in userspace that is based on ping times rather than
    hop count.  (The latter is implemented in firewire-core itself but is
    not applicable to beta PHYs that act as repeater.)
