mlxsw devlink support¶

This document describes the devlink features implemented by the mlxsw device driver.

Parameters¶

Generic parameters implemented¶

Name

Mode

fw_load_policy

driverinit

The mlxsw driver also implements the following driver-specific parameters.

Driver-specific parameters implemented¶

Name

Type

Mode

Description

acl_region_rehash_interval

u32

runtime

Sets an interval for periodic ACL region rehashes. The value is specified in milliseconds, with a minimum of 3000. The value of 0 disables periodic work entirely. The first rehash will be run immediately after the value is set.

The mlxsw driver supports reloading via DEVLINK_CMD_RELOAD

Info versions¶

The mlxsw driver reports the following versions

devlink info versions implemented¶

Name

Type

Description

hw.revision

fixed

The hardware revision for this board

fw.psid

fixed

Firmware PSID

fw.version

running

Three digit firmware version

Line card auxiliary device info versions¶

The mlxsw driver reports the following versions for line card auxiliary device

devlink info versions implemented¶

Name

Type

Description

hw.revision

fixed

The hardware revision for this line card

ini.version

running

Version of line card INI loaded

fw.psid

fixed

Line card device PSID

fw.version

running

Three digit firmware version of line card device

Driver-specific Traps¶

List of Driver-specific Traps Registered by mlxsw¶

Name

Type

Description

irif_disabled

drop

Traps packets that the device decided to drop because they need to be routed from a disabled router interface (RIF). This can happen during RIF dismantle, when the RIF is first disabled before being removed completely

erif_disabled

drop

Traps packets that the device decided to drop because they need to be routed through a disabled router interface (RIF). This can happen during RIF dismantle, when the RIF is first disabled before being removed completely
