Hi, Currently ice driver does not allow creating more than one networking device per physical function. The only way to have more hardware backed netdev is to use SR-IOV.
Following patchset adds support for devlink port API. For each new pcisf type port, driver allocates new VSI, configures all resources needed, including dynamically MSIX vectors, program rules and registers new netdev. This series supports only one Tx/Rx queue pair per subfunction. Example commands: devlink port add pci/0000:31:00.1 flavour pcisf pfnum 1 sfnum 1000 devlink port function set pci/0000:31:00.1/1 hw_addr 00:00:00:00:03:14 devlink port function set pci/0000:31:00.1/1 state active devlink port function del pci/0000:31:00.1/1 Make the port representor and eswitch code generic to support subfunction representor type. VSI configuration is slightly different between VF and SF. It needs to be reflected in the code. Most recent previous patchset (not containing port representor for SF support).
