Neterion: New driver: Ethtool related

This patch implements all ethtool related entry point functions for the driver.

- Changes in this submission -
- Removed redundant #include statements

- Changes in previous submissions -
- Removed unused statistics.
- General clean up - removed unused variables and macros.
- Incorporated following comments from Ben Hutchings
- No need to restart the interface in vxge_ethtool_sset
- Do not use #ifdef ADVERTISED_XX
- Remove unnecessart intermediate copy in vxge_ethtool_gdrvinfo
- Use strlcpy() to ensure null-termination.
- Use ethtool_op_get_tso, ethtool_op_set_tx_hw_csum instead
of redefining the same code.
- Implement get_strings_count instead of deprecated get_stats_count.
- Don't report reporting the EEPROM length as we don't supprt
get/set eeprom.
- Don't set self_test_count as we don't support any self tests.
