  *              Steve Mead <steve.mead at comdev dot cc>
  *     - Port Gleb Natapov's multicast support patchs from 2.4.12
  *       to 2.4.18 adding support for multicast.
+ *
+ * 2002/06/17 - Tony Cureington <tony.cureington * hp_com>
+ *     - corrected uninitialized pointer (ifr.ifr_data) in bond_check_dev_link;
+ *       actually changed function to use ETHTOOL, then MIIPHY, and finally
+ *       MIIREG to determine the link status
+ *     - fixed bad ifr_data pointer assignments in bond_ioctl
+ *     - corrected mode 1 being reported as active-backup in bond_get_info;
+ *       also added text to distinguish type of load balancing (rr or xor)
+ *     - change arp_ip_target module param from "1-12s" (array of 12 ptrs)
+ *       to "s" (a single ptr)
