So far, ifup -a tries to up all non-disabled interfaces in sequence. This can take a quite a while, because interfaces with the link down, will be polled for 10s, before giving up on doing DHCP on them. This series accelerates this in the common case by doing link up check in parallel, getting down from (number_of_ports_wihout_link * 10s) to 10s and then adds an optimization for the common case of automounts with $global.net.server not set.
