- * net/core/ethtool.c - Ethtool ioctl handler
- * Copyright (c) 2003 Matthew Wilcox <matthew@wil.cx>
- *
- * This file is where we call all the ethtool_ops commands to get
- * the information ethtool needs. We fall back to calling do_ioctl()
- * for drivers which haven't been converted to ethtool_ops yet.
- *
- * It's GPL, stupid.
- *
- * Modification by sfeldma@pobox.com to work as backward compat
- * solution for pre-ethtool_ops kernels.
- * - copied struct ethtool_ops from ethtool.h
- * - defined SET_ETHTOOL_OPS
- * - put in some #ifndef NETIF_F_xxx wrappers
- * - changes refs to dev->ethtool_ops to ethtool_ops
- * - changed dev_ethtool to ethtool_ioctl
- * - remove EXPORT_SYMBOL()s
- * - added _kc_ prefix in built-in ethtool_op_xxx ops.
