Hi,

The scenario:
The scenario is:
* Create a bond with 3 interfaces (connect them to switch).
* Change bond's mode to active/backup.
* Physicly remove two cables form interfaces ( not the active interface ).
* Put the cables back
* Change the mode to round robin.
* Try to ping some other computer.

Now only one interface is pinging to remote computer.
Without removing the cables all three interface will ping to remote
computer periodicly.



The problem:
In the kernel 2.6.39.3 ( /drivers/net/bond/bond_main.c).
In the function  ‘bond_xmit_roundrobin’
The code check if the bond is active via
‘bond_is_active_slave(slave)’ Function call.
Which actually checks if the slave is backup or active
What is the meaning of slave being  backup in round robin mode?
Correct me if I wrong but in round robin every slave should send a
packet, regardless of being active or backup.

Thank you,
           Eduard
