[dpdk-dev] [PATCH] net/mlx5: add 200G and 400G link speed

[dpdk-dev] [PATCH] net/mlx5: add 200G and 400G link speed

[Asaf Penso]

There is no way to report back a link speed of 200Gbps nor 400Gbps.

Adding both 200G and 400G link speed.

[dpdk-dev] [PATCH v3] net/mlx5: add 200G link speed

[Asaf Penso]

There is no way to report back a link speed of 200Gbps.

Adding 200G link speed.

Signed-off-by: Asaf Penso <asafp@mellanox.com>
---
v2 - reword commit log and remove 400G

v3 - rebase and fix checkpatch warning

Hi Asaf,

Patch looks good, but it updates ethdev & testpmd to have 200G defines and mlx5
to use it, so net/mlx5 prefix not really fits to the patch, can you separate
mlx5 changes into another patch?

I think I was the one advising to squash all.
The reason is that the changes in testpmd and ethdev are
simple and mechanical.
The real change is in mlx5 in my opinion, but I'm fine with splitting as well.

Agree the real change is in the PMD and rest is mechanical, my concern was if we
need to refer the ethdev or testpmd change later, we will need to use commit
"net/mlx5: ..." which may be confusing.

I think ethdev, testpmd & doc can be combined into one "ethdev: ..." and PMD
implementation into other patch.

Does it make sense?
