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.)

netdev: add per-queue statistics The ethtool-nl family does a good job exposing various protocol related and IEEE/IETF statistics which used to get dumped under ethtool -S, with creative names. Queue stats don't have a netlink API, yet, and remain a lion's share of ethtool -S output for new drivers. Not only is that bad because the names differ driver to driver but it's also bug-prone. Intuitively drivers try to report only the stats for active queues, but querying ethtool stats involves multiple system calls, and the number of stats is read separately from the stats themselves. Worse still when user space asks for values of the stats, it doesn't inform the kernel how big the buffer is. If number of stats increases in the meantime kernel will overflow user buffer. Add a netlink API for dumping queue stats. Queue information is exposed via the netdev-genl family, so add the stats there. Support per-queue and sum-for-device dumps. Latter will be useful when subsequent patches add more interesting common stats than just bytes and packets. The API does not currently distinguish between HW and SW stats. The expectation is that the source of the stats will either not matter much (good packets) or be obvious (skb alloc errors).
