Simulate port function state of a PCI port. This enables users to get and set the state of the PCI port function. Example of a PCI SF port which supports a port function: Create a device with ID=10 and one physical port. $ echo "10 1" > /sys/bus/netdevsim/new_device Add PCI PF port: $ devlink port add netdevsim/netdevsim10 flavour pcipf pfnum 2 netdevsim/netdevsim10/1: type eth netdev eth1 flavour pcipf controller 0 pfnum 2 external false splittable false function: hw_addr 00:00:00:00:00:00 $ devlink port add netdevsim/netdevsim10 flavour pcisf pfnum 2 netdevsim/netdevsim10/2: type eth netdev eth2 flavour pcisf controller 0 pfnum 2 sfnum 0 splittable false function: hw_addr 00:00:00:00:00:00 Show devlink port: $ devlink port show netdevsim/netdevsim10/2 netdevsim/netdevsim10/2: type eth netdev eth2 flavour pcisf controller 0 pfnum 2 sfnum 0 splittable false function: hw_addr 00:00:00:00:00:00 state inactive opstate detached Set the MAC address and activate the function: $ devlink port function set netdevsim/netdevsim10/2 hw_addr 00:11:22:33:44:55 state active Show the port and function attributes in JSON format: $ devlink port show netdevsim/netdevsim10/2 -jp { "port": { "netdevsim/netdevsim10/2": { "type": "eth", "netdev": "eth2", "flavour": "pcisf", "controller": 0, "pfnum": 2, "sfnum": 0, "splittable": false, "function": { "hw_addr": "00:11:22:33:44:55", "state": "active", "opstate": "attached" } } } } Signed-off-by: Parav Pandit <parav@nvidia.com> --- drivers/net/netdevsim/dev.c | 1 + drivers/net/netdevsim/netdevsim.h | 4 ++++ drivers/net/netdevsim/port_function.c | 15 +++++++++++++++ 3 files changed, 20 insertions(+)
