Navdeep Parhar 72cc43df17 Add a knob to allow zero UDP checksums for UDP/IPv6 traffic on the given UDP port.
This will be used by some upcoming changes to if_vxlan(4).  RFC 7348 (VXLAN)
says that the UDP checksum "SHOULD be transmitted as zero.  When a packet is
received with a UDP checksum of zero, it MUST be accepted for decapsulation."
But the original IPv6 RFCs did not allow zero UDP checksum.  RFC 6935 attempts
to resolve this.
