Mainly, the RFC was backed by netdevsim implementation, this is mlxsw with actual HW underneath.

I don't remember any changes in this aspect during the internal review and I also compared the uAPI files and they seem to be the same. The only change that I do remember is making the APIs idempotent. Previously, this would fail: # devlink lc set pci/0000:01:00.0 lc 8 notype # devlink lc set pci/0000:01:00.0 lc 8 notype
Jiri says: This patchset introduces support for modular switch systems and also introduces mlxsw support for NVIDIA Mellanox SN4800 modular switch. It contains 8 slots to accommodate line cards - replaceable PHY modules which may contain gearboxes. Currently supported line card: 16X 100GbE (QSFP28) Other line cards that are going to be supported: 8X 200GbE (QSFP56) 4X 400GbE (QSFP-DD) There may be other types of line cards added in the future. To be consistent with the port split configuration (splitter cabels), the line card entities are treated in the similar way. The nature of a line card is not "a pluggable device", but "a pluggable PHY module". A concept of "provisioning" is introduced. The user may "provision" certain slot with a line card type. Driver then creates all instances (devlink ports, netdevices, etc) related to this line card type. It does not matter if the line card is plugged-in at the time. User is able to configure netdevices, devlink ports, setup port splitters, etc. From the perspective of the switch ASIC, all is present and can be configured. The carrier of netdevices stays down if the line card is not plugged-in. Once the line card is inserted and activated, the carrier of the related netdevices is then reflecting the physical line state, same as for an ordinary fixed port. Once user does not want to use the line card related instances anymore, he can "unprovision" the slot. Driver then removes the instances. Patches 1-4 are extending devlink driver API and UAPI in order to register, show, dump, provision and activate the line card. Patches 5-17 are implementing the introduced API in mlxsw. The last patch adds a selftest for mlxsw line cards. Example: $ devlink port # No ports are listed $ devlink lc pci/0000:01:00.0: lc 1 state unprovisioned supported_types: 16x100G lc 2 state unprovisioned supported_types: 16x100G lc 3 state unprovisioned supported_types: 16x100G lc 4 state unprovisioned supported_types: 16x100G lc 5 state unprovisioned supported_types: 16x100G lc 6 state unprovisioned supported_types: 16x100G lc 7 state unprovisioned supported_types: 16x100G lc 8 state unprovisioned supported_types: 16x100G Note that driver exposes list supported line card types. Currently there is only one: "16x100G".
