* 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)
