+ * Changes:
+ *
+ * 2004/12/12 - Mitch Williams <mitch.a.williams at intel dot com>
+ *	- Initial creation of sysfs interface.
+ *
+ * 2005/06/22 - Radheka Godse <radheka.godse at intel dot com>
+ *	- Added ifenslave -c type functionality to sysfs
+ *	- Added sysfs files for attributes such as  MII Status and
+ *	  802.3ad aggregator that are displayed in /proc
+ *	- Added "name value" format to sysfs "mode" and
+ *	  "lacp_rate", for e.g., "active-backup 1" or "slow 0" for
+ *	  consistency and ease of script parsing
+ *	- Fixed reversal of octets in arp_ip_targets via sysfs
+ *	- sysfs support to handle bond interface re-naming
+ *	- Moved all sysfs entries into /sys/class/net instead of
+ *	  of using a standalone subsystem.
+ *	- Added sysfs symlinks between masters and slaves
+ *	- Corrected bugs in sysfs unload path when creating bonds
+ *	  with existing interface names.
+ *	- Removed redundant sysfs stat file since it duplicates slave info
+ *	  from the proc file
+ *	- Fixed errors in sysfs show/store arp targets.
+ *	- For consistency with ifenslave, instead of exiting
+ *	  with an error, updated bonding sysfs to
+ *	  close and attempt to enslave an up adapter.
+ *	- Fixed NULL dereference when adding a slave interface
+ *	  that does not exist.
+ *	- Added checks in sysfs bonding to reject invalid ip addresses
+ *	- Synch up with post linux-2.6.12 bonding changes
+ *	- Created sysfs bond attrib for xmit_hash_policy
+ *
+ * 2005/09/19 - Mitch Williams <mitch.a.williams at intel dot com>
+ *	- Changed semantics of multi-item files to be command-based
+ *	  instead of list-based.
+ *	- Changed ARP target handler to use in_aton instead of sscanf
+ *      - Style changes.
+ * 2005/09/27 - Mitch Williams <mitch.a.williams at intel dot com>
+ *      - Made line endings consistent.
+ *      - Removed "none" from primary output - just put blank instead
+ *      - Fixed bug with long interface names
