Hi All
I'm running tests from https://github.com/linux-rdma/rdma-core/tree/master and
got the following errors from all tests.test_mlx5_dc.DCTest tests:
build/bin/run_tests.py --dev mlx5_2 --port 1 tests.test_mlx5_dc.DCTest.test_dc_rdma_write

Additional information:
- VF is LAG and VF binds to host.
- DC tests fail when NIC is in switchdev mode while legacy mode is fine.
- Tested on 5.12 inbox driver or OFED 5.3, neither is working.
- 5f:00.0 Ethernet controller [0200]: Mellanox Technologies MT2892 Family [ConnectX-6 Dx] [15b3:101d]
- firmware-version: 22.30.1004 (MT_0000000536)
I worked a bit tracepoint on 5.12 inbox driver. It seems like there's a firmware
command error for CREATE_DCT.
I can provide more information if you ask.
Thanks

Is there any syndrome in kernel log? Try to reproduce with debug log
enabled:
echo -n "func mlx5_cmd_check +p" > /sys/kernel/debug/dynamic_debug/control
