Add support for 'dscp' selector in ip-rule.
Rules can be added with a numeric DSCP value:
# ip rule add dscp 1 table 100
# ip rule add dscp 0x02 table 200
Or using symbolic names from /usr/share/iproute2/rt_dsfield or
/etc/iproute2/rt_dsfield:
# ip rule add dscp AF42 table 300
Dump output:
$ ip rule show
0: from all lookup local
32763: from all lookup 300 dscp AF42
32764: from all lookup 200 dscp 2
32765: from all lookup 100 dscp 1
32766: from all lookup main
32767: from all lookup default
Dump can be filtered by DSCP value:
$ ip rule show dscp 1
32765: from all lookup 100 dscp 1
Or by a symbolic name:
$ ip rule show dscp AF42
32763: from all lookup 300 dscp AF42
When the numeric option is specified, symbolic names will be translated
to numeric values:
$ ip -N rule show
0: from all lookup 255
32763: from all lookup 300 dscp 36
32764: from all lookup 200 dscp 2
32765: from all lookup 100 dscp 1
32766: from all lookup 254
32767: from all lookup 253
The same applies to the JSON output in order to be consistent with
existing fields such as "tos" and "table":
$ ip -j -p rule show dscp AF42
[ {
"priority": 32763,
"src": "all",
"table": "300",
"dscp": "AF42"
} ]
$ ip -j -p -N rule show dscp AF42
[ {
"priority": 32763,
"src": "all",
"table": "300",
"dscp": "36"
} ]
