ynl: broaden the license even more I relicensed Netlink spec code to GPL-2.0 OR BSD-3-Clause but we still put a slightly different license on the uAPI header than the rest of the code. Use the Linux-syscall-note on all the specs and all generated code. It's moot for kernel code, but should not hurt. This way the licenses match everywhere.

netdev-genl: create a simple family for netdev stuff Add a Netlink spec-compatible family for netdevs. This is a very simple implementation without much thought going into it. It allows us to reap all the benefits of Netlink specs, one can use the generic client to issue the commands: $ ./cli.py --spec netdev.yaml --dump dev_get [{'ifindex': 1, 'xdp-features': set()}, {'ifindex': 2, 'xdp-features': {'basic', 'ndo-xmit', 'redirect'}}, {'ifindex': 3, 'xdp-features': {'rx-sg'}}] the generic python library does not have flags-by-name support, yet, but we also don't have to carry strings in the messages, as user space can get the names from the spec.

net: ynl: prefix uAPI header include with uapi/ To keep things simple we used to include the uAPI header in the kernel in the #include <linux/$family.h> format. This works well enough, most of the genl families should have headers in include/net/ so linux/$family.h ends up referring to the uAPI header, anyway. And if it doesn't no big deal, we'll just include more info than we need. Unless that is there is a naming conflict. Someone recently created include/linux/psp.h which will be a problem when supporting the PSP protocol. (I'm talking about work-in-progress patches, but it's just a proof that assuming lack of name conflicts was overly optimistic.)
