Hello,
can somebody please tell me whether lpbk_mode works for mellanox NICs?
I found 65c9d24170c9 ("net/mlx5: enable loopback by configured mode")
that seems to implement this feature for mlx5. But setting lpbk_mode in
rte_eth_conf does not seem to work for me (ixgbe works with this).
Are there any other ways how to configure such HW loopback-mode
mellanox NICs (both mlx5, mlx4)?
Thanks
Jan

Hello Jan,
The feature is expected to work.
Let's work offline to get more details and once we conclude we can post here the outcome.

We checked again and saw the feature is not fully working.
A BZ ticket was opened for that - https://bugs.dpdk.org/show_bug.cgi?id=645
