Hi,
I have ConnectX-6 (MCX653106A-HDAT) NIC and try to use DPDK mlx5_crypto
driver for crypto offload. I've followed the instructions provided in
the documentation (https://doc.dpdk.org/guides/cryptodevs/mlx5.html),
but unfortunately, I've encountered some problems along the way.
The main issue I am experiencing is the inability to switch the NIC to
crypto operational mode. I am facing a failure in the first step:
```
mlxreg -d /dev/mst/mt4123_pciconf0 --reg_name CRYPTO_OPERATIONAL --get
Sending access register...
-E- Failed to send access register: ME_ICMD_OPERATIONAL_ERROR
```
I use:
- MLX_OFED 5.8-2.0.3.0
- fw 20.35.2000
- I set the CRYPTO_POLICY configuration value to 2 (it also does not
work with 1 value)
lsmod | grep mlx output:
```
mlx5_ib 450560 0
mlx5_core 2039808 1 mlx5_ib

rdma_cm,ib_ipoib,mlxdevm,iw_cm,ib_umad,ib_core,rdma_ucm,ib_uverbs,mlx5_ib,ib_cm,mlx5_core
```
Could you please advise me how to solve the problem and what steps to
take to successfully use this driver?
Thank you.
