2019-06-30igmp: accept packets that have more on the wire data than IGMP reports.Neale Ranns1-3/+19
IGMPv3 sends a variable length of sources in a query. Today if the amount of data on the wire does not exactly match that required for the number of sources the packet is dropped. Relax this check and instead accept the packet is the amount of wire data is equal or greater than the number of sources. Some devices on the wild internet pad small packets.

2018-06-29IP4 Router Alert option handling for IGMPNeale Ranns1-1/+5
and a new ip4-options node, inserted between ip4-input and ip4-punt, that checks for IP-router-alert option + IGMP combination and sends the packet to the ip4-local. This is required because some IGMP packets are sent to the group address and not the all-routers address. All IGMP packets are sent with the router alert option.
