The Pim RFC does not appear to state any length requirements of pim, other than the checksum must be correct. Certain vendors are sending extra data at the end of a pim assert message. This while not explicitly against the rules was a bit of surprise to pim when we threw the assert message on the floor for being too long. Modify the test to see if length left will allow us to read the 8 bytes of data that we need. If it is sufficient for that allow the packet to be used.

INTRODUCTION
qpimd aims to implement a PIM (Protocol Independent Multicast)
daemon for the FRR Routing Suite.
qpimd implements PIM-SM (Sparse Mode) of RFC 4601.
Additionally MSDP has been implemented.
In order to deliver end-to-end multicast routing control
plane, qpimd includes the router-side of IGMPv[2|3] (RFC 3376).
