devlink: Extend SF port attributes to have external attribute
Extended SF port attributes to have optional external flag similar to PCI PF and VF port attributes. External atttibute is required to generate unique phys_port_name when PF number and SF number are overlapping between two controllers similar to SR-IOV VFs. When a SF is for external controller an example view of external SF port and config sequence. On eswitch system: $ devlink dev eswitch set pci/0033:01:00.0 mode switchdev $ devlink port show pci/0033:01:00.0/196607: type eth netdev enP51p1s0f0np0 flavour physical port 0 splittable false pci/0033:01:00.0/131072: type eth netdev eth0 flavour pcipf controller 1 pfnum 0 external true splittable false function: hw_addr 00:00:00:00:00:00 $ devlink port add pci/0033:01:00.0 flavour pcisf pfnum 0 sfnum 77 controller 1 pci/0033:01:00.0/163840: type eth netdev eth1 flavour pcisf controller 1 pfnum 0 sfnum 77 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached phys_port_name construction: $ cat /sys/class/net/eth1/phys_port_name c1pf0sf77 Signed-off-by: Parav Pandit <parav@nvidia.com> Reviewed-by: Jiri Pirko <jiri@nvidia.com> Reviewed-by: Vu Pham <vuhuong@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
