Add support for __be64 and bitops, centralize several needed macros
This change is meant to add support for __be64 values and bitops to
ethtool. In addition the patch pulls the SIOCETHTOOL define and the
ARRAY_SIZE define into ethtool-util.h for later use by the rxclass files.
These changes will be needed in order to support network flow
classifier rule configuration.
