Error loading drbd_transport_rdma.ko module

[Indivar Nair]

Hello All,

I have a 2-node cluster on which I am trying to load the
drdb_transport_rdma.ko modules.

The nodes have -
- Rocky Linux 9.1 (Kernel 5.14.0-162.23.1)
- NVIDIA/Mellanox ConnectX-5 EN 100GB NIC
- MLNX_OFED_LINUX-23.10-3.2.2.0-rhel9.1-x86_64 drivers
- DRBD 9.2.3 (compiled on the same machine)

I have connected the 100G ports back-to-back with a short DAC cable.
Tests with perftest tools (ib_send_bw and ib_read_bw) show proper
connectivity. RoCE is working properly.

But, I get the following error when I try to load the
drdb_transport_rdma.ko module
