The man pages for nfs in FC4 list udp as the default protocol for nfsv4:

       proto=n        Mount the NFS filesystem using a specific network proto-
                      col instead of the default UDP protocol.  Many NFS  ver-
                      sion  4  servers only support TCP.  Valid protocol types
                      are udp and tcp.

and for v2/3:

       tcp            Mount the NFS filesystem using the TCP protocol  instead
                      of the default UDP protocol.  Many NFS servers only sup-
                      port UDP.

       udp            Mount the NFS filesystem using the UDP  protocol.   This
                      is the default.
