Subject: [PATCH RESEND iproute2 net-next 0/4] devlink rate support
Date: Wed, 2 Jun 2021 15:31:01 +0300 [thread overview]
Message-ID: <1622637065-30803-1-git-send-email-dlinkin@nvidia.com> (raw)
In-Reply-To: <1622636251-29892-1-git-send-email-dlinkin@nvidia.com>
Resending without RFC.
Serries implements devlink rate commands, which are:
- Dump particular or all rate objects (JSON or non-JSON)
- Add/Delete node rate object
- Set tx rate share/max values for rate object
- Set/Unset parent rate object for other rate object
Examples:
Display all rate objects:
# devlink port function rate show
pci/0000:03:00.0/1 type leaf parent some_group
pci/0000:03:00.0/2 type leaf tx_share 12Mbit
pci/0000:03:00.0/some_group type node tx_share 1Gbps tx_max 5Gbps
Display leaf rate object bound to the 1st devlink port of the
pci/0000:03:00.0 device:
# devlink port function rate show pci/0000:03:00.0/1
pci/0000:03:00.0/1 type leaf
Display node rate object with name some_group of the pci/0000:03:00.0
device:
# devlink port function rate show pci/0000:03:00.0/some_group
pci/0000:03:00.0/some_group type node
Display leaf rate object rate values using IEC units:
# devlink -i port function rate show pci/0000:03:00.0/2
pci/0000:03:00.0/2 type leaf 11718Kibit
Display pci/0000:03:00.0/2 leaf rate object as pretty JSON output:
# devlink -jp port function rate show pci/0000:03:00.0/2
{
"rate": {
"pci/0000:03:00.0/2": {
"type": "leaf",
"tx_share": 1500000
}
}
}
Create node rate object with name "1st_group" on pci/0000:03:00.0 device:
# devlink port function rate add pci/0000:03:00.0/1st_group
Create node rate object with specified parameters:
# devlink port function rate add pci/0000:03:00.0/2nd_group \
tx_share 10Mbit tx_max 30Mbit parent 1st_group
Set parameters to the specified leaf rate object:
# devlink port function rate set pci/0000:03:00.0/1 \
tx_share 2Mbit tx_max 10Mbit
Set leaf's parent to "1st_group":
# devlink port function rate set pci/0000:03:00.0/1 parent 1st_group
Unset leaf's parent:
# devlink port function rate set pci/0000:03:00.0/1 noparent
Delete node rate object:
# devlink port function rate del pci/0000:03:00.0/2nd_group
Rate values can be specified in bits or bytes per second (bit|bps), with
any SI (k, m, g, t) or IEC (ki, mi, gi, ti) prefix. Bare number means
bits per second. Units also printed in "show" command output, but not
necessarily the same which were specified with "set" or "add" command.
-i/--iec switch force output in IEC units. JSON output always print
values as bytes per sec.
