Add implementation for the port parameters
getting/setting.
Add bash completion for port param.
Add man description for port param.
Example:
$ devlink dev param set netdevsim/netdevsim0/0 name test_port_parameter value
false cmode runtime
$ devlink port param show netdevsim/netdevsim0/0 name test_port_parameter
netdevsim/netdevsim0/0:
name test_port_parameter type driver-specific
values:
cmode runtime value false
$ devlink port -jp param show netdevsim/netdevsim0/0 name test_port_parameter
{
"param": {
"netdevsim/netdevsim0/0": [ {
"name": "test_port_parameter",
"type": "driver-specific",
"values": [ {
"cmode": "runtime",
"value": false
} ]
} ]
}
}
