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 :) -- Dominique
