To restore your slaves' MAC addresses, you need to detach them
from the bond (`ifenslave -d bond0 eth0'), set them down
(`ifconfig eth0 down'), unload the drivers (`rmmod 3c59x', for
example) and reload them to get the MAC addresses from their
eeproms. If the driver is shared by several devices, you need
to turn them all down. Another solution is to look for the MAC
address at boot time (dmesg or tail /var/log/messages) and to
reset it by hand with ifconfig :
# ifconfig eth0 down
# ifconfig eth0 hw ether 00:20:40:60:80:A0

restore the MAC addresses that the slaves had before they were enslaved.

8021q VLAN support
==================
It is possible to configure VLAN devices over a bond interface using the 8021q
driver. However, only packets coming from the 8021q driver and passing through
bonding will be tagged by default. Self generated packets, like bonding's
learning packets or ARP packets generated by either ALB mode or the ARP
monitor mechanism, are tagged internally by bonding itself. As a result,
bonding has to "learn" what VLAN IDs are configured on top of it, and it uses
those IDs to tag self generated packets.
For simplicity reasons, and to support the use of adapters that can do VLAN
hardware acceleration offloding, the bonding interface declares itself as
fully hardware offloaing capable, it gets the add_vid/kill_vid notifications
to gather the necessary information, and it propagates those actions to the
slaves.
In case of mixed adapter types, hardware accelerated tagged packets that should
go through an adapter that is not offloading capable are "un-accelerated" by the
bonding driver so the VLAN tag sits in the regular location.
VLAN interfaces *must* be added on top of a bonding interface only after
enslaving at least one slave. This is because until the first slave is added the
bonding interface has a HW address of 00:00:00:00:00:00, which will be copied by
the VLAN interface when it is created.
Notice that a problem would occur if all slaves are released from a bond that
still has VLAN interfaces on top of it. When later coming to add new slaves, the
bonding interface would get a HW address from the first slave, which might not
match that of the VLAN interfaces. It is recommended that either all VLANs are
removed and then re-added, or to manually set the bonding interface's HW
address so it matches the VLAN's. (Note: changing a VLAN interface's HW address
would set the underlying device -- i.e. the bonding interface -- to promiscouos
mode, which might not be what you want).

* In the following 3 functions, bond_vlan_rx_register(), bond_vlan_rx_add_vid
* and bond_vlan_rx_kill_vid, We don't protect the slave list iteration with a
* lock because:
* a. This operation is performed in IOCTL context,
* b. The operation is protected by the RTNL semaphore in the 8021q code,
* c. Holding a lock with BH disabled while directly calling a base driver
* entry point is generally a BAD idea.
*
* The design of synchronization/protection for this operation in the 8021q
* module is good for one or more VLAN devices over a single physical device
* and cannot be extended for a teaming solution like bonding, so there is a
* potential race condition here where a net device from the vlan group might
* be referenced (either by a base driver or the 8021q code) while it is being
* removed from the system. However, it turns out we're not making matters
* worse, and if it works for regular VLAN usage it will work here too.
