Taku Izumi says:

====================
FUJITSU Extended Socket driver version 1.2

This patchset updates FUJITSU Extended Socket network driver into version 1.2.
This includes the following enhancements:
  - ethtool -d support
  - ethtool -S enhancement
  - ethtool -w/-W support
  - Add some debugging feature (tracepoints etc)

v1 -> v2:
  - Use u64 instead of phys_addr_t as TP_STRUCT__entry
  - Use ethtool facility to achieve debug mode instead of using debugfs
====================
