Monitoring RoCE Packets

I am writing FPGA code to send RoCEv2 packets to an Intel E810-based network adapter. When I properly form the Ethernet/IP4/UDP headers, Wireshark no longer captures any packets. When I send an incorrect IP4 checksum, the packets reappear. Is this due to the network card bypassing the kernel?

Please update the question with the output of wireshark -v
This will show version information for Wireshark, the operating system and capture library.
