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.

Add new helper function print_bool_opt() which prints
with no prefix and use it for vxlan options.
If the option matches the expected default value,
it is not printed if in non JSON mode unless the details
setting is repeated.
Use a table for the vxlan options. This will change
the order of the printing of options.

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.

Add a new function rtnl_echo_talk() that could be used when the
sub-component supports NLM_F_ECHO flag. With this function we can
remove the redundant code added by commit b264b4c656 ("ip: add
NLM_F_ECHO support").

There is no rule to have an error code after NLMSG_DONE msg. The only reason
we has this offset is that kernel function netlink_dump_done() has an error
code followed by the netlink message header.
Making nl_dump_ext_ack_done() has an offset parameter. So we can adjust
this for NLMSG_DONE message without error code.

When user space configures the kernel with netlink messages, it can set the
NLM_F_ECHO flag to request the kernel to send the applied configuration back
to the caller. This allows user space to retrieve configuration information
that are filled by the kernel (either because these parameters can only be
set by the kernel or because user space let the kernel choose a default
value).
NLM_F_ACK is also supplied incase the kernel doesn't support NLM_F_ECHO
and we will wait for the reply forever. Just like the update in
iplink.c, which I plan to post a patch to kernel later.
A new parameter -echo is added when user want to get feedback from kernel.
e.g.
# ip -echo addr add 192.168.0.1/24 dev eth1
3: eth1 inet 192.168.0.1/24 scope global eth1
valid_lft forever preferred_lft forever
# ip -j -p -echo addr del 192.168.0.1/24 dev eth1

mnlu_gen_socket_open opens a socket and configures it for use with a
generic netlink family. As part of this process it sends a
CTRL_CMD_GETFAMILY to get the ID for the family name requested.
In addition to the family id, this command reports a few other useful
values including the maximum attribute. The maximum attribute is useful in
order to know whether a given attribute is supported and for knowing the
necessary size to allocate for other operations such as policy dumping.
Since we already have to issue a CTRL_CMD_GETFAMILY to get the id, we can
also store the maximum attribute as well. Modify the callback functions to
parse the maximum attribute NLA and store it in the mnlu_gen_socket
structure.
