Issue resolved.
Mellanox NICs in all my Ubuntu 18.x PCs were set to RoCEv2 mode, while NICs in my 17.10 PCs were running at default mode. I have verified that, if the NIC in the wireshark PC is running at default mode, we can always capture RDMA packets. If the NIC is running at RoCEv2 mode, then no RDMA packet will be captured. This has nothing to do with Ubuntu or kernel versions.
Thanks for the discussions. Some of your comments/questions prompt me to look into the NIC mode.
