    nfsd: Update the rc.d script for RDMA for the nfsd service
    
    Commit 7144a1d58c5c added the hooks for the nfsrdma.ko module.
    Once loaded, this module adds RDMA support to the nfsd.
    
    This patch adds a few lines to /etc/rc.d/nfsd, so that
    nfs_server_rdma_enable="YES"
    in your /etc/rc.conf will load nfsrdma.ko, so that RDMA
    service is enabled.
    It also supports
    nfs_server_rdma_listen="port#"
    so that the default of 20490 can be overridden in /etc/rc.conf.
    
    At this available as time, the nfsrdma.ko module is an unofficial port,
    since it was developed by Vinicius Ferrao <ferrao@versatushpc.com.br>
    using generative AI.
    As soon as it is available, it will be announced on
    freebsd-current@freebsd.org.
