Nope, 10GbE packets are exactly like normal ethernet packets, they
just come faster. Wireshark normally uses the interface in promiscuous
mode, which means you'll get the packets no matter where they're
destined. You've definitely got IP addresses and ports setup properly?
Then this sounds like it could be a labview problem.
To check, try your labview code with another computer: netcat a UDP
packet to your labview receiver and see if you can see that. If you
don't have another computer with a 10GbE interface, you can use ROACH
and tgtap. tgtap will start a normal-looking network interface on
ROACH. You can ping and netcat through it like any other interface.
Here is a ROACH with two 10gbe interfaces configured (ie two instances
of tgtap):

Hi All,
I just bought a 10Gb ethernet card (Chelsio S310E), but I got
problems with receiving udp packages.
I installed the card and drivers for a windows computer, everything
is fine, the 10Gb card looks just like another normal network local
connection. Then I ran Jason's 10GbE tutorial design on roach board,
instead of loop back connection (from port 1 to port 3), I
connected the roach 10Gb port 1 directly to the windows computer.
I ran a LabVIEW program to receive the udp packets just like I did
before for receiving udp packets from fast ethernet port. But I
didn't receive any udp packets.
I checked with Wireshark, I can see all the packets, and the data
are also right number (linear increasing number in Jason's design).
I just can not receive them in my LabVIEW program.
Is there any difference between 10Gb and fast ethernet udp packets?
