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

The mlxsw driver reports the following versions

Name	Type	Description
`hw.revision`	fixed	The hardware revision for this board
`fw.psid`	fixed	Firmware PSID
`fw.version`	running	Three digit firmware version

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

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
