2024-12-17ice: rename devlink_port.[ch] to port.[ch]Przemek Kitszel
Drop "devlink_" prefix from files that sit in devlink/. I'm going to add more files there, and repeating "devlink" does not feel good. This is also the scheme used in most other places, most notably the devlink core files are named like that. devlink.[ch] stays as is.

2024-09-06ice: subfunction activation and base devlink opsPiotr Raczynski
Use previously implemented SF aux driver. It is probe during SF activation and remove after deactivation. Implement set/get hw_address and set/get state as basic devlink ops for subfunction.

2024-09-06ice: support subfunction devlink Tx topologyMichal Swiatkowski
Flow for creating Tx topology is the same as for VF port representors, but the devlink port is stored in different place (sf->devlink_port). When creating VF devlink lock isn't taken, when creating subfunction it is. Setting Tx topology function needs to take this lock, check if it was taken before to not do it twice.

2024-09-06ice: create port representor for SFMichal Swiatkowski
Implement attaching and detaching SF port representor. It is done in the same way as the VF port representor. SF port representor is always added or removed with devlink lock taken.

2024-09-06ice: base subfunction aux driverPiotr Raczynski
Implement subfunction driver. It is probe when subfunction port is activated. VSI is already created. During the probe VSI is being configured. MAC unicast and broadcast filter is added to allow traffic to pass. Store subfunction pointer in VSI struct. The same is done for VF pointer. Make union of subfunction and VF pointer as only one of them can be set with one VSI.

2024-09-06ice: add basic devlink subfunctions supportPiotr Raczynski
Implement devlink port handlers responsible for ethernet type devlink subfunctions. Create subfunction devlink port and setup all resources needed for a subfunction netdev to operate. Configure new VSI for each new subfunction, initialize and configure interrupts and Tx/Rx resources. Set correct MAC filters and create new netdev. For now, subfunction is limited to only one Tx/Rx queue pair. Only allocate new subfunction VSI with devlink port new command. Allocate and free subfunction MSIX interrupt vectors using new API calls with pci_msix_alloc_irq_at and pci_msix_free_irq. Support both automatic and manual subfunction numbers. If no subfunction number is provided, use xa_alloc to pick a number automatically. This will find the first free index and use that as the number. This reduces burden on users in the simple case where a specific number is not required. It may also be slightly faster to check that a number exists since xarray lookup should be faster than a linear scan of the dyn_ports xarray.

2024-08-20ice: use internal pf id instead of function numberMichal Swiatkowski
