    This ipvs package adds Linux IP Virtual Server capability to OpenWRT
    IPVS (IP Virtual Server) implements transport-layer load balancing inside the Linux kernel, so called Layer-4 switching.
IPVS running on a host acts as a load balancer at the front of a cluster of real servers, it can direct requests for
TCP/UDP based services to the real servers, and makes services of the real servers to appear as a virtual service on a
single IP address.

    This patch enables configuration of the IP Virtual Server kernel modules
