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.
