Indeed, this turns out to be enabled by WITH_OFED. It then uses the Makefile in contrib/ofed/include/rdma to install headers, and the Makefile in contrib/ofed/usr.lib/librdmacm to install a library. Unfortunately the headers aren't compatible with the qemu requirements, so the port still needs to have --disable-rdma, in any case. -Dimitry
