Implement user commands to manage devlink port func rate objects.
List all rate commands:
$ devlink port func rate help
or just
$ devlink port func rate
To list all OR particular rate object:
$ devlink port func rate show
pci/0000:03:00.0/some_group: type node
pci/0000:03:00.0/0: type leaf
pci/0000:03:00.0/1: type leaf
$ devlink prot func rate show pci/0000:03:00.0/1
pci/0000:03:00.0/0: type leaf
$ devlink prot func rate show pci/0000:03:00.0/some_group
pci/0000:03:00.0/some_group: type node
Rate object of type "leaf" created by it's driver where name is the name
of corresponding devlink port. Rate object of type "node" represents
rate group created by the user using commands:
$ devlink port func rate add pci/0000:03:00.0/some_group
or with defining tx rate limits
$ devlink port func rate add pci/0000:03:00.0/some_group \
tx_shara 10kbit tx_max 100mbit
NOTE: node name cannot be a decimal value because it conflicts with
devlink port indexes.
To delete node object:
$ devlink port func rate del pci/0000:03:00.0/some_group
Set rate limits of existing rate object:
$ devlink prot func rate set pci/0000:03:00.0/0 \
tx_share 5MBps tx_max 25GBps
$ devlink prot func rate set pci/0000:03:00.0/some_group \
tx_share 0
Both SET and ADD commands accept any units of rates defined in IEC
60027-2 standard.
NOTE: rate value 0 means that rate is unlimited. Such value is also
ommited in show command output.
NOTE: In SHOW command output rate values will be printed with suffixes
as well, but in JSON output they are always units of Bps.
Set or unset parent of existing rate object:
$ devlink prot func rate set pci/0000:03:00.0/0 parent some_group
$ devlink port func rate set pci/0000:03:00.0/0 noparent
NOTE: Setting parent to empty ("") name due to kernel logic means unset
parent and shouldn't be used to avoid unexpected parent unsets.

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. include/uapi
This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
