Adding a new NSPU command for being able to read and write the ethernet port table from/to the NFP. This will allow the PMD to put the Link up or down when a port is started or stopped. Until now, this was performed by the firmware independently of PMD functionality. The ethernet port table has also some other useful information that will be used in further commits. Usually NSPU is used at device probe time and that is sequential code execution. However, reading and writing the NFP eth table can be done at different times and from different cores, and it implies it could happen a concurrent access. A spinlock is added to the global nspu object for protecting the NFP and avoiding the concurrent access. Signed-off-by: Alejandro Lucero <alejandro.lucero@netronome.com> |
