Hi Hans,

pls don't commit them. 
I've forgot the SOB line, but also would like to add a GPG signature to
it, after you've reviewed them.

Best,
lynxis

Curious: what purposes or use-cases are intended to be served with this event ?

Please don't top post

The interface event IFEV_CREATE can be used by external applications
or netifd internal subsystems to trigger specific logic when an
interface is created; patch http://patchwork.ozlabs.org/patch/937167/
makes use of this event
