[ Upstream commit a2f61f1db85532e72fb8a3af51b06df94bb82912 ]
The port header is a general file under include, yet it
contains declarations for functions that are either not
exported or exported but not used outside the mlx5_core
driver.
To enhance code organization, we move these declarations
to mlx5_core.h, where they are more appropriately scoped.
This refactor removes unnecessary exported symbols and
prevents unexported functions from being inadvertently
referenced outside of the mlx5_core driver.

Support the new "plane_ind" field when querying port PTYS registers.
This is needed when querying the rate of a plane port.

net/mlx5: Parse module mapping using mlx5_ifc2022-03-11T07:38:25+00:00Gal Pressmangal@nvidia.com2022-01-17T13:53:06+00:00urn:sha1:fcb610a86c53dfcfbb2aa62e704481112752f367
The assumption that the first byte in the module mapping dword is the
module number shouldn't be hard-coded in the driver, but come from
mlx5_ifc structs.
While at it, fix the incorrect width for the 'rx_lane' and 'tx_lane'
fields.
