This series simulates one or more PCI PF and SF port addition and function configuration functionality.
Example sequence: 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" } } } } Delete PCI SF and PF ports: $ devlink port del netdevsim/netdevsim10/2 Patch summary: patch-1 adds support for adding/remove PCI PF port patch-2 adds support for adding/remove PCI SF port patch-3 simulates MAC address query patch-4 simulates setting MAC address patch-5 simulates state query patch-6 simulates setting state patch-7 adds tests Parav Pandit (7): netdevsim: Add support for add and delete of a PCI PF port netdevsim: Add support for add and delete PCI SF port netdevsim: Simulate get hardware address of a PCI port netdevsim: Simulate set hardware address of a PCI port netdevsim: Simulate port function state for a PCI port netdevsim: Simulate port function set state for a PCI port netdevsim: Add netdevsim port add test cases drivers/net/netdevsim/Makefile | 2 +- drivers/net/netdevsim/dev.c | 14 + drivers/net/netdevsim/netdevsim.h | 38 ++ drivers/net/netdevsim/port_function.c | 521 ++++++++++++++++++ .../drivers/net/netdevsim/devlink.sh | 72 ++- 5 files changed, 645 insertions(+), 2 deletions(-) create mode 100644 drivers/net/netdevsim/port_function.c -- 2.26.2
