fail_over_mac
Specifies whether active-backup mode should set all slaves to
the same MAC address (the traditional behavior), or, when
enabled, change the bond's MAC address when changing the
active interface (i.e., fail over the MAC address itself).
Fail over MAC is useful for devices that cannot ever alter
their MAC address, or for devices that refuse incoming
broadcasts with their own source MAC (which interferes with
the ARP monitor).
The down side of fail over MAC is that every device on the
network must be updated via gratuitous ARP, vs. just updating
a switch or set of switches (which often takes place for any
traffic, not just ARP traffic, if the switch snoops incoming
traffic to update its tables) for the traditional method. If
the gratuitous ARP is lost, communication may be disrupted.
When fail over MAC is used in conjuction with the mii monitor,
devices which assert link up prior to being able to actually
transmit and receive are particularly susecptible to loss of
the gratuitous ARP, and an appropriate updelay setting may be
required.
A value of 0 disables fail over MAC, and is the default. A
value of 1 enables fail over MAC. This option is enabled
automatically if the first slave added cannot change its MAC
address. This option may be modified via sysfs only when no
slaves are present in the bond.
This option was added in bonding version 3.2.0.
