In the recent change to avoid an mbuf allocation on locally generated UDP
packets, I updated the mbuf length but not the pkthdr length on the mbuf.
This resulted in an inconcistency between the length of the mbuf and the
length of the mbuf chain that was caught by the checksum validation code
on the loopback interface, but appeared only to affect "large" UDP
packets. I've committed a fix, please let me know if this eliminates this
issue for you.
