New network test failure on jenkins

[Edward Haas]

Hi Nir,

The test scans all bond options for all modes.
It does it by modifying all the bond options values and checking the result.

We saw the same problem before and fixed it by recreating 
the bond device per mode. The problem did not reappeared until now.
We suspect it is a bond module issue/timing.

Has it happen to you more than once?

We could try something like this: If it fails on EBUSY, redo the scan 
from the mode that failed. (hoping that removing and adding the bond
will resolve it)

Thanks,
Edy.
