    network: prevent interfaces to be initialized multiple times

    When a uevent is received during the relevant interface is in
    LINK_STATE_PENDING, then the interface may be initialized twice.
    To prevent that, this introduces LINK_STATE_INITIALIZED.

I'll triage further and possibly revert the change in the next 243-based upload.

I suspect this is actually a dup of bug 1860926

[Balint Reczey (rbalint)]

Yes, indeed.
Including the change from LP: #1860926 the reverts can be dropped.

As I wrote in LP: #1860926 I'd like to include your fix in the next upload to Groovy even if upstream would like to find a different solution.
