From: Frank Blaschka <frank.blaschka@de.ibm.com>
List of major changes and improvements:
no manipulation of the global ARP constructor
clean code split into core, layer 2 and layer 3 functionality
better exploitation of the ethtool interface
better representation of the various hardware capabilities
fix packet socket support (tcpdump), no fake_ll required
osasnmpd notification via udev events
coding style and beautification
