  14. * 2003/03/18 - Amir Noam <amir.noam at intel dot com>
  15. * - Added support for getting slave's speed and duplex via ethtool.
  16. * Needed for 802.3ad and other future modes.
  17. *
  18. * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
  19. * Shmulik Hen <shmulik.hen at intel dot com>
  20. * - Enable support of modes that need to use the unique mac address of
  21. * each slave.
  22. *
  23. * 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
  24. * Amir Noam <amir.noam at intel dot com>
  25. * - Moved driver's private data types to bonding.h
  26. *

  28. * Tsippy Mendelson <tsippy.mendelson at intel dot com> and
  29. * Shmulik Hen <shmulik.hen at intel dot com>
  30. * - Added support for IEEE 802.3ad Dynamic link aggregation mode.
  31. *
  32. * 2003/05/01 - Amir Noam <amir.noam at intel dot com>
  33. * - Added ABI version control to restore compatibility between
  34. * new/old ifenslave and new/old bonding.
  35. *
  36. * 2003/12/01 - Shmulik Hen <shmulik.hen at intel dot com>
  37. * - Code cleanup and style changes
  38. *
  39. * 2005/05/05 - Jason Gabler <jygabler at lbl dot gov>
  40. * - added definitions for various XOR hashing policies
