The function rtnl_addproto_a2n() was defined but never used.
Use it to allow for symbolic names, and fix the function signatures
so protocol value is consistently __u8.

IPv4 and IPv6 addresses can be assigned a protocol value that indicates the
provenance of the IP address. The attribute is modeled after ip route
protocols, and essentially allows the administrator or userspace stack to
tag addresses in some way that makes sense to the actor in question.
Support for this feature was merged with commit 47f0bd503210 ("net: Add new
protocol attribute to IP addresses"), for kernel 5.18.
In this patch, add support for setting the protocol attribute at IP address
addition, replacement, and listing requests.
An example session with the feature in action:
# ip address add dev d 192.0.2.1/28 proto 0xab
# ip address show dev d
26: d: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 06:29:74:fd:1f:eb brd ff:ff:ff:ff:ff:ff
inet 192.0.2.1/28 scope global proto 0xab d
valid_lft forever preferred_lft forever
# ip address replace dev d 192.0.2.1/28 proto 0x11
# ip address show dev d
26: d: <BROADCAST,NOARP> mtu 1500 qdisc noop state DOWN group default qlen 1000
link/ether 06:29:74:fd:1f:eb brd ff:ff:ff:ff:ff:ff
inet 192.0.2.1/28 scope global proto 0x11 d
valid_lft forever preferred_lft forever
A JSON dump. The protocol value is always provided as a string, even in
numeric mode, to provide a consistent interface.
# ip -j address show dev d | jq

PPP protocol field uses different values than ethertype. Introduce
utilities for translating PPP protocols from strings to values
and vice versa. Use generic API from utils in order to get
proto id and name.

For formatting DSCP (not full dsfield), it would be handy to be able to
just get the name from the name table, and not get any of the remaining
cruft related to formatting. Add a new entry point to just fetch the
name table string uninterpreted. Use it from rtnl_dsfield_n2a().

This patch adds support for recently
added link IFLA_PROTO_DOWN_REASON attribute.
IFLA_PROTO_DOWN_REASON enumerates reasons
for the already existing IFLA_PROTO_DOWN link
attribute.

Note: for somereason the json and non-json key for protodown
are different (protodown and proto_down). I have kept the
same for protodown reason for consistency (protodown_reason and
proto_down_reason).

There were only few Netlink protocol names
which were printed on the screen:

So added the ability to identify Netlink proto name
from /etc/iproute/nl_protos or from static table.

This change adds the interface group to the output of "ip link show".
It also makes "ip link" print _all_ devices if no group filter is specified;
previously, only interfaces of the default group (0) were shown.

User can specify device group to list by using the group keyword:
ip link show group test
If no group is specified, 0 (default) is implied.

[IPROUTE]: Add support for larger number of routing tables
Support support for 2^32 routing tables by using the new RTA_TABLE
attribute for specifying tables > 255 and intepreting it if it is
sent by the kernel.
When tables > 255 are used on a kernel not supporting it an error will
occur because of the unknown netlink attribute.
