Subject: [PATCH ethtool v5 0/6] ethtool(1) cable test support

Add the user space side of the ethtool cable test.

The TDR output is most useful when fed to some other tool which can
visualize the data. So add JSON support, by borrowing code from
iproute2.

v2:
man page fixes.

v3:
More man page fixes.
Use json_print from iproute2.

v4:
checkpatch cleanup
ethtool --cable-test dev
Place breakout into cable_test_context
Remove Pair: Pair output

v5:
Add missing pair in help text
Allow --cable-test|--cable-test-tdr with --monitor
Fix rounding when converting from floating point meters to centimeters

Andrew Lunn (6):
  Add cable test support
  Add cable test TDR support
  json_writer: Import the iproute2 helper code for JSON output
  Add --json command line argument parsing
  ethtool.8.in: Document the cable test commands
  ethtool.8.in: Add --json option
