Patch #1 updates the UAPI headers.

Patch #2 adds the actual implementation that allows user space to set
transceiver modules' low power mode. See the commit message for example
output.

Patches #3-#5 parse more fields from SFF-8636 and CMIS EEPROMs to
provide better observability regarding the low power mode of the
modules.

Patch #6 adds the ability to reset transceiver modules. See the commit
message for example usage.

Ido Schimmel (6):
  Update UAPI header copies
  ethtool: Add ability to control transceiver modules' low power mode
  ethtool: Print CMIS Module State
  ethtool: Print CMIS Module-Level Controls
  ethtool: Print SFF-8636 Power set and Power override bits
  ethtool: Add ability to reset transceiver modules
