DESCRIPTION¶
devlink port set - change devlink port attributes¶
DEV/PORT_INDEX - specifies the devlink port to operate on.
Format is:
BUS_NAME/BUS_ADDRESS/PORT_INDEX
- type { eth | ib | auto }
- set port type
eth - Ethernet
ib - Infiniband
auto - autoselect
devlink port split - split devlink port into more¶
DEV/PORT_INDEX - specifies the devlink port to operate on.
- count COUNT
- number of ports to split to.
devlink port unsplit - unsplit previously split devlink port¶
Could be performed on any split port of the same split group.
DEV/PORT_INDEX - specifies the devlink port to operate on.
devlink port show - display devlink port attributes¶
DEV/PORT_INDEX - specifies the devlink port to show. If this argument is omitted all ports are listed.
devlink port health - devlink health reporting and recovery¶
Is an alias for devlink-health(8).
devlink port add - add a devlink port¶
DEV - specifies the devlink device to operate on. or
DEV/PORT_INDEX - specifies the devlink port index to use for the requested new port. This is optional. When omitted, driver allocates unique port index.
- flavour { pcipf | pcisf }
- set port flavour
pcipf - PCI PF port
pcisf - PCI SF port
- pfnum PFNUMBER
- Specifies PCI pfnumber to use on which a SF device to create
- sfnum SFNUMBER
- Specifies sfnumber to assign to the device of the SF. This field is optional for those devices which supports auto assignment of the SF number.
- controller CNUM
- Specifies controller number for which the SF port is created. This field is optional. It is used only when SF port is created for the external controller.
devlink port function set - Set the port function attribute(s).¶
DEV/PORT_INDEX - specifies the devlink port to operate on.
- hw_addr ADDR
- Hardware address of the function to set. This is a Ethernet MAC address when port type is Ethernet.
- state { active | inactive }
- New state of the function to change to.
active - Once configuration of the function is done, activate the function.
inactive - To inactivate the function and its device(s), set to inactive.
- roce { enable | disable }
- Set the RoCE capability of the function.
- migratable { enable | disable }
- Set the migratable capability of the function.
devlink port del - delete a devlink port¶
DEV/PORT_INDEX - specifies the devlink port to delete.
devlink port param set - set new value to devlink port configuration parameter¶
DEV/PORT_INDEX - specifies the devlink port to operate on.
- name PARAMETER
- Specify parameter name to set.
- value VALUE
- New value to set.
- cmode { runtime | driverinit | permanent }
- Configuration mode in which the new value is set.
runtime - Set new value while driver is running. This configuration mode doesn't require any reset to apply the new value.
driverinit - Set new value which will be applied during driver initialization. This configuration mode requires restart driver by devlink reload command to apply the new value.
permanent - New value is written to device's non-volatile memory. This configuration mode requires hard reset to apply the new value.
devlink port param show - display devlink port supported configuration parameters attributes¶
DEV/PORT_INDEX - specifies the devlink port to operate on.
name PARAMETER Specify parameter name to show. If this argument, as well as port index, are omitted - all parameters supported by devlink device ports are listed.
devlink port function rate - manage devlink rate objects¶
Is an alias for devlink-rate(8).
