+ * Code 930.5, Goddard Space Flight Center, Greenbelt MD 20771
+ *
+ * Changes :
+ * - 2000/10/02 Willy Tarreau <willy at meta-x.org> :
+ * - few fixes. Master's MAC address is now correctly taken from
+ * the first device when not previously set ;
+ * - detach support : call BOND_RELEASE to detach an enslaved interface.
+ * - give a mini-howto from command-line help : # ifenslave -h
+ *
+ * - 2001/02/16 Chad N. Tindel <ctindel at ieee dot org> :
+ * - Master is now brought down before setting the MAC address. In
+ * the 2.4 kernel you can't change the MAC address while the device is
+ * up because you get EBUSY.
+ *
+ * - 2001/09/13 Takao Indoh <indou dot takao at jp dot fujitsu dot com>
+ * - Added the ability to change the active interface on a mode 1 bond
+ * at runtime.
+ *
+ * - 2001/10/23 Chad N. Tindel <ctindel at ieee dot org> :
+ * - No longer set the MAC address of the master. The bond device will
+ * take care of this itself
+ * - Try the SIOC*** versions of the bonding ioctls before using the
+ * old versions
+ * - 2002/02/18 Erik Habbinga <erik_habbinga @ hp dot com> :
+ * - ifr2.ifr_flags was not initialized in the hwaddr_notset case,
+ * SIOCGIFFLAGS now called before hwaddr_notset test
+ *
+ * - 2002/10/31 Tony Cureington <tony.cureington * hp_com> :
+ * - If the master does not have a hardware address when the first slave
+ * is enslaved, the master is assigned the hardware address of that
+ * slave - there is a comment in bonding.c stating "ifenslave takes
+ * care of this now." This corrects the problem of slaves having
+ * different hardware addresses in active-backup mode when
+ * multiple interfaces are specified on a single ifenslave command
+ * (ifenslave bond0 eth0 eth1).
+ *
+ * - 2003/03/18 - Tsippy Mendelson <tsippy.mendelson at intel dot com> and
+ * Shmulik Hen <shmulik.hen at intel dot com>
+ * - Moved setting the slave's mac address and openning it, from
+ * the application to the driver. This enables support of modes
+ * that need to use the unique mac address of each slave.
+ * The driver also takes care of closing the slave and restoring its
+ * original mac address upon release.
+ * In addition, block possibility of enslaving before the master is up.
+ * This prevents putting the system in an undefined state.
+ *
+ * - 2003/05/01 - Amir Noam <amir.noam at intel dot com>
+ * - Added ABI version control to restore compatibility between
+ * new/old ifenslave and new/old bonding.
+ * - Prevent adding an adapter that is already a slave.
+ * Fixes the problem of stalling the transmission and leaving
+ * the slave in a down state.
+ *
+ * - 2003/05/01 - Shmulik Hen <shmulik.hen at intel dot com>
+ * - Prevent enslaving if the bond device is down.
+ * Fixes the problem of leaving the system in unstable state and
+ * halting when trying to remove the module.
+ * - Close socket on all abnormal exists.
+ * - Add versioning scheme that follows that of the bonding driver.
+ * current version is 1.0.0 as a base line.
+ *
+ * - 2003/05/22 - Jay Vosburgh <fubar at us dot ibm dot com>
+ * - ifenslave -c was broken; it's now fixed
+ * - Fixed problem with routes vanishing from master during enslave
+ * processing.
+ *
+ * - 2003/05/27 - Amir Noam <amir.noam at intel dot com>
+ * - Fix backward compatibility issues:
+ * For drivers not using ABI versions, slave was set down while
+ * it should be left up before enslaving.
+ * Also, master was not set down and the default set_mac_address()
+ * would fail and generate an error message in the system log.
+ * - For opt_c: slave should not be set to the master's setting
+ * while it is running. It was already set during enslave. To
+ * simplify things, it is now handeled separately.
