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
