[PATCH] ip-pnp-dhcp: wait lazily when doing dhcp for diskless systems
ic_dynamic() holds the cpu too long and tasks do not have a chance to run.
This causes adapters like e1000 that have the link come up in a tasklet to fail
link up due to exceptionally long delays in acquiring link, and then a dhcp
address.
