Hi Ian,
The patch only notify around peer how to reach it when network
circumstance changed.
I don't know what's wrong about the patch (the new feature isn't
proper or the patch have other problem)?
Why do any body ask the issue?
Thanks,
Jason

The
patch main to fix the below circumstance:
Bonding run in Active-Backup mode.
Out PC --> switcher
port A --> eth0 --> bond0 --> xenbr0 -->
netbackend --> DomU
port B -- eth1 /
Or
Out PC (R)--> switcher A --> eth0 --> bond0 -->
xenbr0 --> netbackend --> DomU
\ switcher B -- eth1 /
When Switcher Port A (active port) don't reach, or switcher A
don't reach,
the surroundings will changed to the below circumstance.
Out PC --> switcher
port A -X- eth0 -- bond0 -- xenbr0 -- netbackend --
DomU
port B -- eth1 /
Or
Out PC (R)--> switcher A -X- eth0 -- bond0 -- xenbr0 --
netbackend -- DomU
\ switcher B -- eth1 /
So, the former traffic will be unreachable before find the
correct path (by sending
ARP request).
So, the patch is main to found the bonding change event, and
gratutious ARP initialtivly
to out PC find the correct path.
the correct path should be the below circumstance:
Out PC --> switcher
port A -X- eth0 --> bond0 --> xenbr0 -->
netbackend --> DomU
port B --> eth1 /
Or
Out PC (R)--> switcher A -X- eth0 --> bond0 --> xenbr0
--> netbackend --> DomU
\ switcher B --> eth1 /
Thanks,
Jason
