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.
