Felix Fietkau 2f43d3dcba igmpproxy: add patch to silence unnecessary logging of downstream igmp traffic
This patch adds a simple check to silence logging of messages about
unrecognized igmp packets which originate from devices in local network.

Without this patch igmpproxy floods openwrt syslog with messages such as:
  user.warn igmpproxy[19818]: The source address 192.168.1.175 for group
  239.255.250.250, is not in any valid net for upstream VIF.
