From 1897db2ec3109eb1dd07b357c95c5e03d54e41b9 Mon Sep 17 00:00:00 2001 From: Dmytro Linkin Date: Wed, 2 Jun 2021 15:17:22 +0300 Subject: devlink: Allow setting tx rate for devlink rate leaf objects Implement support for DEVLINK_CMD_RATE_SET command with new attributes DEVLINK_ATTR_RATE_TX_{SHARE|MAX} that are used to set devlink rate shared/max tx rate values. Extend devlink ops with new callbacks rate_leaf_tx_{share|max}_set() to allow supporting drivers to implement rate control through devlink. New attributes are optional. Driver implementations are allowed to support either or both of them. Shared rate example: $ devlink port function rate set netdevsim/netdevsim10/0 tx_share 10mbit $ devlink port function rate show netdevsim/netdevsim10/0 netdevsim/netdevsim10/0: type leaf tx_share 10mbit Max rate example: $ devlink port function rate set netdevsim/netdevsim10/0 tx_max 100mbit $ devlink port function rate show netdevsim/netdevsim10/0 netdevsim/netdevsim10/0: type leaf tx_max 100mbit Co-developed-by: Vlad Buslov Signed-off-by: Vlad Buslov Signed-off-by: Dmytro Linkin Reviewed-by: Jiri Pirko Signed-off-by: David S.
