Format is:
BUS_NAME/BUS_ADDRESS/PORT_INDEX
type { eth | ib | auto }
set port type

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.
ipsec_crypto { enable | disable }
Set the IPsec crypto offload capability of the function.
Controls XFRM state crypto operation (Encrypt/Decrypt)
offload.
ipsec_packet { enable | disable }
Set the IPsec packet offload capability of the function.
Controls XFRM state and policy offload (Encrypt/Decrypt
operation and IPsec encapsulation).
max_io_eqs EQS
Set the maximum number of IO event queues 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).
devlink port show
Shows the state of all devlink ports on the system.
devlink port show pci/0000:01:00.0/1
Shows the state of specified devlink port.
devlink port set pci/0000:01:00.0/1 type eth
Set type of specified devlink port to Ethernet.
devlink port split pci/0000:01:00.0/1 count 4
Split the specified devlink port into four ports.
devlink port unsplit pci/0000:01:00.0/1
Unplit the specified previously split devlink port.
devlink port health show
Shows status and configuration of all supported reporters
registered on all devlink ports.
devlink port health show pci/0000:01:00.0/1 reporter tx
Shows status and configuration of tx reporter registered on
pci/0000:01:00.0/1 devlink port.
devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
Add a devlink port of flavour PCI SF on PCI PF having number
0 with SF number 88. To make use of the function an example
sequence is to add a port, configure the function attribute
and activate the function. Once function usage is completed,
inactivate the function and finally delete the port. When
there is desire to reuse the port without deletion, it can be
reconfigured and activated again when function is in inactive
state and function's operational state is detached.
devlink port del pci/0000:06:00.0/1
Delete previously created devlink port. It is recommended to
first deactivate the function if the function supports state
management.
devlink port function set pci/0000:01:00.0/1 hw_addr
00:00:00:11:22:33
Configure hardware address of the PCI function represented by
devlink port. If the port supports change in function state,
hardware address must be configured before activating the
function.
devlink port function set pci/0000:01:00.0/1 state active
Activate the function. This will initiate the function
enumeration and driver loading.
devlink port function set pci/0000:01:00.0/1 state inactive
Deactivate the function. This will initiate the function
teardown which results in driver unload and device removal.
devlink port function set pci/0000:01:00.0/1 roce enable
This will enable the RoCE functionality of the function.
devlink port function set pci/0000:01:00.0/1 migratable enable
This will enable the migratable functionality of the
function.
devlink port function set pci/0000:01:00.0/1 ipsec_crypto enable
This will enable the IPsec crypto offload functionality of
the function.
devlink port function set pci/0000:01:00.0/1 ipsec_packet enable
This will enable the IPsec packet offload functionality of
the function.
devlink port function set pci/0000:01:00.0/1 max_io_eqs 4
This will set the maximum number of IO event queues of the
function to 4.
devlink port function set pci/0000:01:00.0/1 hw_addr
00:00:00:11:22:33 state active
Configure hardware address and also active the function. When
a function is activated together with other configuration in
a single command, all the configuration is applied first
before changing the state to active.
devlink dev param show
Shows (dumps) all the port parameters across all the devices
registered in the devlink.
devlink dev param set pci/0000:01:00.0/1 name
internal_error_reset value true cmode runtime
Sets the parameter internal_error_reset of specified devlink
port (#1) to true.
devlink port add pci/0000:06:00.0 flavour pcisf pfnum 0 sfnum 88
controller 1
Add a devlink port of flavour PCI SF on controller 1 which
has PCI PF of number 0 with SF number 88. To make use of the
function an example sequence is to add a port, configure the
function attribute and activate the function. Once the
function usage is completed, deactivate the function and
finally delete the port. When there is desire to reuse the
port without deletion, it can be reconfigured and activated
again when function is in inactive state and function's
operational state is detached.
