I don't know. I believe the first step is the todo list items
https://darnassus.sceen.net/~hurd-web/contributing/
“
- Make sure that lwip supports configuration by DHCP.
- Extensively test (e.g. running testsuites of glibc, perl, curl, rust-mio) and fix the lwip-based TCP/IP stack, to be sure we don't get regressions by switching to it.
”
(again, for the second point, it's *regressions* I'm talking about. It's
fine to see some tests fail if they were already failing with pfinet,
it's possibly just outside of the pfinet/lwip area. What we don't want
is regressing).
and then it's about figuring out how to do the transition. There's the
set up for new installs in debian/local/setup-translators. We'll want to
migrate existing installs in debian/hurd.postinst. There's also the
debian-installer code in netcfg and netcfg-static that will need fixing.
Possibly others, apparently mmdebstrap and crosshurd too.

Are you using isc-dhcp? You have the latest snapshot on
http://snapshot.debian.org/package/isc-dhcp/4.4.3-P1-1.1%2Bhurd.2/
which is what I used to build on hurd-amd64.
