The inability to include the uAPI headers directly in tools/
is one of the bigger annoyances of compiling user space code.
Most projects trade the pain for smaller inconvenience of having
to copy the headers under tools/include.
In case of netlink headers I think that we can avoid both.
Netlink family headers are simple and should be self-contained.
We can try to twiddle the Makefile a little to force-include
just the family header, and use system headers for the rest.
This works fairly well. There are two warts - for some reason
if we specify -include $path/family.h as a compilation flag,
the #ifdef header guard does not seem to work. So we need
to throw the guard in on the command line as well. Seems like
GCC detects that the header is different and tries to include
both. Second problem is that make wants hash sign to be escaped
or not depending on the version. Sigh.

Generate the protocol code for ethtool. Skip the stats
for now, they are the only outlier in terms of complexity.
Stats are a sort-of semi-polymorphic (attr space of a nest
depends on value of another attr) or a type-value-scalar,
depending on how one wants to look at it...
A challenge for another time.

This reverts commit e7c5433c5a.
Commit e7c5433c5a ("tools: ynl: Remove duplicated include
in handshake-user.c") was applied too hastily. It changes
an auto-generated file, and there's already a proper fix
on the list.

Admittedly the devlink.yaml spec is fairly limitted,
it only covers basic device get and info-get ops.
That's sufficient to be useful (monitoring FW versions
in the fleet). Plus it gives us a chance to exercise
deep nesting and directional messaging in YNL.

In preparation for supporting families which use different msg
ids to and from the kernel - make sure the ids in op strmap
are correct. The map is expected to be used mostly for notifications,
don't generate a separate map for the "to kernel" direction.

Generate the code for netdev and fou families. They are simple
and already supported by the code gen.

Add "fixed" part of the user space Netlink Spec-based library.
This will get linked with the protocol implementations to form
a full API.
