IPVS: one-packet scheduling
Allow one-packet scheduling for UDP connections. When the fwmark-based or normal virtual service is marked with '-o' or '--ops' options all connections are created only to schedule one packet. Useful to schedule UDP packets from same client port to different real servers. Recommended with RR or WRR schedulers (the connections are not visible with ipvsadm -L).
