The patch below restores compatibility that was removed during the
propagation set. That set added the ability to set the bond's hardware
address in the conventional way using SIOCSIFHWADDR but also removed
support for the very old way using BOND_SETHWADDR, which, although has
been removed from the ifenslave code for years, turns out to still be
in use in the ifenslave binary of recent distributions.

The patch applies on 2.4.23-pre5 and should also cleanly apply on
2.6.0-test6 after fully applying the propagation set (patch 2 wasn't
applied yet).

Jeff, please apply this patch soon so that 2.4.23 won't be released
with a bug that breaks compatibility.
