Steven Polley ead7578544 change pcap snaplen to 126 bytes 
We really only care getting as far as the UDP header and can discard the rest.  This should reduce load, and perhaps enable full pcap with ports on the BPF filter

UDP header = 8 bytes
IPv4 max size = 60 bytes
IPv6 fixed size = 40 bytes
Ethernet header size = 18 bytes
