Not AFAICT in IPv6 :
rfc2460 :
o Unlike IPv4, when UDP packets are originated by an IPv6 node,
the UDP checksum is not optional. That is, whenever
originating a UDP packet, an IPv6 node must compute a UDP
checksum over the packet and the pseudo-header, and, if that
computation yields a result of zero, it must be changed to hex
FFFF for placement in the UDP header. IPv6 receivers must
discard UDP packets containing a zero checksum, and should log
the error.
Of course, this decision was taken in parallel with the decision to drop
the IP header checksum from IPv6. Nobody was quite ready to 100% trust
the link layer.
