Christopher, I just saw that you have removed the tag '6wind'.
I'm not sure how this field should be used, but it was useful to tag bugs opened by our company with that tag ('6wind') to be able to find them easily. Is there a way to found all bugs opened by someone and/or a company? For example all bugs reported by someone with an email that ends with '@6wind.com'?

Thank you,
Nicolas

  A netlink message advertise that bond0 is deleted and after that two
  netlink messages are sent telling that bond0 exists again.
