mod/bridge-port-to: re-enable interfaces with longer delay...•••... and in one go to limit the overall runtime.
Looks like IPv6 addresses are not flushed if the link down does not last
long enough (~ 2 seconds on linux). This results on stale addresses
after switching bridge, which breaks connectivity.
log-forward: do *not* wait to be fully connected•••Let's forward logs as early as possible.
All notification functions are expected to handle notifications with
queues, so nothing is lost. Just the opposite: Logs being rotated before
forwarding becomes less likely.
