Patch for ip setting on bridge interface and vlan

Patch for ip setting on bridge interface and vlan

[Kevin Yung]

Hi all,

I have an environment that needs to boot on bridged interface or 
interface using vlan. 

I found curent dracut release will by pass ip settings on these interfaces. 

So I wrote the a patch to set up provided ip options on the interfaces 
that using bridge or vlan. 

Please let me know if I need to tidy it up a bit more or 
add additional code to handle ip settings on bridge 

and vlan.

Cheers
Kevin
