Add support for 'flowlabel' selector in ip-rule.
Rules can be added with or without a mask in which case exact match is
used:
# ip -6 rule add flowlabel 0x12345 table 100
# ip -6 rule add flowlabel 0x11/0xff table 200
# ip -6 rule add flowlabel 0x54321 table 300
# ip -6 rule del flowlabel 0x54321 table 300
Dump output:
$ ip -6 rule show
0: from all lookup local
32764: from all lookup 200 flowlabel 0x11/0xff
32765: from all lookup 100 flowlabel 0x12345
32766: from all lookup main
Dump can be filtered by flow label value and mask:
$ ip -6 rule show flowlabel 0x12345
32765: from all lookup 100 flowlabel 0x12345
$ ip -6 rule show flowlabel 0x11/0xff
32764: from all lookup 200 flowlabel 0x11/0xff
JSON output:
$ ip -6 -j -p rule show flowlabel 0x12345
[ {
"priority": 32765,
"src": "all",
"table": "100",
"flowlabel": "0x12345",
"flowlabel_mask": "0xfffff"
} ]
$ ip -6 -j -p rule show flowlabel 0x11/0xff
[ {
"priority": 32764,
"src": "all",
"table": "200",
"flowlabel": "0x11",
"flowlabel_mask": "0xff"
} ]

Compatibility
-------------
A new release of iproute2 is done with each kernel version, but
there is a wide range of compatibility. Newer versions of iproute2
will still work with older kernels, but there are some limitations.
If an iproute2 command with a new feature is used with an older
kernel, the kernel may report an error or silently ignore the new
attribute. Likewise if older iproute2 is used with an newer kernel,
it is not possible to use or see new features. The range of
compatibility extends back as far as the oldest supported Long Term
Support (LTS) kernel version.
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.
