net: wangxun: Add the basic ethtool interfaces

Browse Source 
Add the basic ethtool ops get_drvinfo and get_link for ngbe and txgbe.
Ngbe implements get_link_ksettings, nway_reset and set_link_ksettings
for free using phylib code.
The code related to the physical interface is not yet fully implemented
in txgbe using phylink code. So do not implement get_link_ksettings,
nway_reset and set_link_ksettings in txgbe.
