Bug#414117: unmerge 414117 537271

[Robert Edmonds <edmonds@debian.org>]

unmerge 414117 537271
reopen 537271
thanks

#414117 was closed due to this change in netcfg:

   * Wait for up to 3 seconds (in 0.25s increments) looking for the link on
     an interface.  Add a progress bar to show the progress of this
     operation.  Closes: #414117.

#537271 concerns the situation where the link is up but not yet usable:

    the debian-installer seems to assume that the network is usable as
    soon as the link comes up, which may not be the case if the 802.1d
    spanning tree protocol is in use, in which case it can be up to ~30
    seconds before the switch port will forward ethernet frames.

please don't merge unrelated bugs.
