Does this mean it would be wise from an interoperability perspective to
extend and evolve the dhcpagent interface so that dhcpagent doesn't do
any SIOCS* ioctls?
That way NWAM could let the DHCP client state machine run through the 4
packet exchange, and then choose which lease it might like to use, and
then tell dhcpagent to release the others?
We could do this and have
ifconfig xx0 dhcp start
work the same; means ifconfig would need to get the address, netmask,
broadcast address, default route(?) from dhcpagent and do the SIOCS* ioctls.
The alternative (which is less work) is to hope that all DHCP servers
that matter will provide the domain name in the offer/advertise message.
