bonding: Add "follow" option to fail_over_mac
Add a "follow" selection for fail_over_mac. This option
causes the MAC address to move from slave to slave as the active
slave changes. This is in addition to the existing fail_over_mac option
that causes the bond's MAC address to change during failover.
This new option is useful for devices that cannot tolerate
multiple ports using the same MAC address simultaneously, either
because it confuses them or incurs a performance penalty (as is the
case with some LPAR-aware multiport devices). Because the MAC of the
bond itself does not change, the "follow" option is slightly more
reliable during failover and doesn't change the MAC of the bond during
operation.
This patch requires a previous ARP monitor change to properly
handle RTNL during failovers.
