What does netstat -s say in the UDP and IP sections?
What does tcpdump say about the checksums of the incoming UDP datagrams
which are not being given to your application?
If you happen to send a UDP datagram from the local host to your
application, is it received? That is, sending a UDP datagram to your
application via some path that does not go through this NIC?
Does your NIC claim to support checksum offload?
Just what is your NIC?
