We are talking about this bit from RFC 3530 ?
Where an NFS version 4 implementation supports operation over the IP
network protocol, the supported transports between NFS and IP MUST be
among the IETF-approved congestion control transport protocols, which
include TCP and SCTP.
This gives most of RDMA an out as it is not over the IP protocol. The
only obvious troubled one is RoCEv2..
