Comment 1 Weiping Pan 2012-04-11 07:01:32 UTC

Hi, Liang Zheng,

IMHO, this is not a bug. 
I think eth0.3 has a loose relationship with eth0, they can have different settings.
It is not like bonding, that bonding device has a close relationship with its slaves.

P.S.
The behaviour is the same in upstream.

thanks

I have discussed with Weiping before,but I donet agree him.
There is some discussion on upstream, you can refer it :
http://patchwork.ozlabs.org/patch/153551/

Comment 6 Weiping Pan 2012-05-04 02:02:02 UTC

The suggested patch has not been accepted in upstream.
I will pay attention to the discussion and then decide whether it is a bug and how to handle it.

Hi,

From the comments in [1], the maintainers do not think this is a bug,
so I will close it.
