Subject: [PATCH net-next v2 0/3] mlxsw: spectrum_buffers: Add the ability to query the CPU port's shared buffer
From: Ido Schimmel <idosch@...lanox.com>
Shalom says:
While debugging packet loss towards the CPU, it is useful to be able to
query the CPU port's shared buffer quotas and occupancy.
Patch #1 prevents changing the CPU port's threshold and binding.
Patch #2 registers the CPU port with devlink.
Patch #3 adds the ability to query the CPU port's shared buffer quotas and
occupancy.
v2:
Patch #1:
* s/0/MLXSW_PORT_CPU_PORT/
* Assign "mlxsw_sp->ports[MLXSW_PORT_CPU_PORT" at the end of
mlxsw_sp_cpu_port_create() to avoid NULL assignment on error path
* Add common functions for mlxsw_core_port_init/fini()
Patch #2:
* Move "changing CPU port's threshold and binding" check to a separate
patch
