net/mlx5: Expose port speed when possible
|
|
|
d8f823 |
|
|
|
d8f823 |
When port speed can't be reported based on ext_eth_proto_capability
|
|
|
d8f823 |
or eth_proto_capability instead of reporting speed as unknown check
|
|
|
d8f823 |
if the port's speed can be inferred based on the data_rate_oper field.
