For TCP, we can probably piggyback on what nfs does for this, see the
ip= parameter in Documentation/admin-guide/nfs/nfsroot.rst -- it lives
in net/ipv4/ipconfig.c so should just work out of the box
For RDMA I'm less optimistic, technically if we can setup ipoib with an
ip with the same parameter it should work, but I have nothing to test it
on anyway so that'll wait until someone who cares actually does try...
Either way, we've got to start somewhere, so it's good there's something :)
