    net: ethtool: Allow PHY cable test TDR data to configured · f2bc8ad3
    Andrew Lunn authored
    Allow the user to configure where on the cable the TDR data should be
    retrieved, in terms of first and last sample, and the step between
    samples. Also add the ability to ask for TDR data for just one pair.
    
    If this configuration is not provided, it defaults to 1-150m at 1m
    intervals for all pairs.
