An idea ... if 'nfs_server_maxio' already sets the 'vfs.nfsd.srvmaxio' maybe it should automatically also set 'kern.ipc.maxsockbuf' to 4*nfs_server_maxio first?

I mean ... if someone wants to just use /etc/rc.conf for this - that seams reasonable ... and if someone uses /etc/sysctl.conf file instead - he will have both of them there anyway and will not use 'nfs_server_maxio' option:

    vfs.nfsd.srvmaxio=ASD
    kern.ipc.maxsockbuf=8*ASD
