The `class_id_max` is wrong due to `tmp.sort` of Strings
If we have class 5 and class 10 we get sorted max value 5, expected 10
```
>>> tmp = ['5', '10']
>>> tmp.sort()
>>> tmp
['10', '5']
>>>
>>> hex(5+1)
'0x6'
>>>
>>> hex(10+1)
'0xb'
>>>
```
This way we get wrong default maximum class value:
```
tc qdisc replace dev eth1 root handle 1: htb r2q 444 default 6
```
Expect:
```
tc qdisc replace dev eth1 root handle 1: htb r2q 444 default b
```
Fix this converting Strings to Integers and get max value.

The current calculation `r2q` is wrong as it uses `Floor division`
but expecting `division`
This way `math.ceil` calculate wrong value as we expect
round a number upward to its nearest integer
For example for speed 710 mbits expected value `444` but we get `443`
```
from math import ceil
MAXQUANTUM = 200000
speed = 710000000
speed_bps = int(speed) // 8
>>> speed_bps // MAXQUANTUM
443
>>> speed_bps / MAXQUANTUM
443.75
>>>
>>>
>>> ceil(speed_bps // MAXQUANTUM)
443
>>> ceil(speed_bps / MAXQUANTUM)
444
>>>
```

qos: T5848: Add triple-isolate option to CAKE policy config
|
|
The default `bandwidth` and `ceiling` should calculate values
based on <tag> bandwidth but currently it gets the value from
qos.base `/sys/class/net/{self._interface}/speed`
```
set qos policy shaper SHAPER bandwidth '20mbit'
set qos policy shaper SHAPER default bandwidth '95%'
set qos policy shaper SHAPER default ceiling '100%'
```
It causes wrong calculations for class `default` i.e
950Mbit for bandwidth (expected 95% of bandwidth, 19Mbit)
1Gbit for ceil (expected 100% of bandwidth, 20Mbit)
Gets incorrect values
```
r4# tc class show dev eth1
class htb 1:1 root rate 20Mbit ceil 20Mbit burst 1600b cburst 1600b
class htb 1:a parent 1:1 leaf 8053: prio 0 rate 200Kbit ceil 200Kbit burst 1Mb cburst 1600b
class htb 1:b parent 1:1 leaf 8054: prio 7 rate 950Mbit ceil 1Gbit burst 15200b cburst 1375b
```
Fix this

T5958: QoS add basic implementation of policy shaper-hfsc
|
|
If we have QoS policy shaper class match `vif` (VLAN) we have to
use `basic match "meta(vlan mask 0xfff eq xxx)` instead of
`action policy`
Actual incorrect TC filter:
tc filter add dev eth1 parent 1: protocol all prio 1 action police rate 100000000 burst 15k flowid 1:64
The correct TC filter after fix:
tc filter add dev eth1 parent 1: protocol all prio 1 basic match "meta(vlan mask 0xfff eq 100)" flowid 1:64

It is impossible to detect interface speed for some devices
for exmaple virtio interfaces:
```
vyos@r4:~$ cat /sys/class/net/eth1/speed
-1
```
It causes wrong negative calcultaions like:
- bandwidth: -1000000
- 4% of bandwidth: -40000
tc class replace dev eth1 parent 1: classid 1:1 htb rate -1000000
tc class replace dev eth1 parent 1:1 classid 1:a htb rate -40000
Fix this with checking negative value.
Add default interface speed to 1000 Mbit if we cannot detect the
interface speed, the current default value 10 Mbit is too low
for nowadays

QoS policy shaper-hfsc was not implemented after rewriting the
traffic-policy to qos policy. We had CLI but it does not use the
correct class. Add a basic implementation of policy shaper-hfsc.
Write the class `TrafficShaperHFS`
|
|
|
|
Add missed option `ceil` for QoS class 'trafficshaper'
|
|
|
|
Fix tc qdisc command that use 'limit None' if limit is not
in config
Limit xx sould be used only if it exists in the config

Prevent duplicatte prio fot tc command
|
|
QoS index priority should be used only for qostype 'shaper'
otherwise we set priority 2 times, that is incorrect.
OSError: [Errno 255] failed to run command:
tc filter add dev eth2 parent 1: prio 5 protocol all prio 1 u32 match ip src 10.1.1.0/24 flowid 1:1e
exit code: 255
Fix it

Fix QoS tc class with multiple matches generates one rule but
expects multiple filter rules:
set qos policy shaper test class 23 match one ip protocol 'tcp'
set qos policy shaper test class 23 match two ip protocol 'udp'
tc filter add dev eth0 parent 1: protocol all prio 1 u32 match ip protocol 6 0xff flowid 1:17
tc filter add dev eth0 parent 1: protocol all prio 2 u32 match ip protocol 17 0xff flowid 1:17
|
|
tc filter rate limit should be used only if qostype is 'limiter'
and not 'shaper'
|
|
QoS DSCP match is skipped
Add it
set qos policy shaper test class 23 match 10 ip dscp 'network'
tc filter replace dev eth0 parent 1: protocol all u32 match ip dsfield 224 0xff flowid 1:17

T5296: Fix QoS class bandwidth calculation for auto and percent
|
|
tc filter exepcts protocol number for match instead of protocol name
|
|
There are wrong bandwidth calculations for the class
We shouldn't rely on interface speed but we should get this value
from 'shaper <tag> bandwidth xxx' if configured 'auto' or
bandwidth with '%'
Otherwise we can get unexpected rate for the class
% sudo cat /sys/class/net/eth0/speed
% -1
generated rate:
classid 1:17 htb rate -1000000
Fix this

Do not handle rate via 'tc filter' directly but rather set the
'tc filter' to direct traffic to the correct tc class flow.
As it in 1.3.
It fixes random unexpected shapes, when you set for example 300mbit
but get 3-11mbit
Current implementation seems not correct as it uses rate limits
two times (in class and in filter):
tc class replace dev eth0 parent 1:1 classid 1:17 htb rate 250000000 \
burst 15k quantum 1514
tc filter replace dev eth0 parent 1: protocol all u32 match \
ip dst 192.168.122.11 action police rate 250000000 burst 15k flowid 1:17
The correct way after fix:
tc class replace dev eth0 parent 1:1 classid 1:17 htb rate 250000000 \
burst 15k quantum 1514
tc filter replace dev eth0 parent 1: protocol all u32 match \
ip dst 192.168.122.11 flowid 1:17

Not all interfaces have valid entries in the speed file. PPPoE interfaces have
the appropriate speed file, but you can not read it:
cat: /sys/class/net/pppoe7/speed: Invalid argument
|

This makes transitions/updates faster and less error prone
