I don't think it's good practise to make ath9k_htc break with older firmware versions so quickly, especially if there's no technical reason. The best would be to wait few months (maybe six?) before forcing the new version, that way user space has time to catch up. Maybe for now you could add a warning about using old firmware version?
Yeah, let's have it warn for a month or two. There's some pending work that will break the API with 1.3 firmware, so it has to happen sooner rather than later. But yeah, maybe warn for about a month would be good. the older firmware is still in the git tree in case people want it. -adrian -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Let me resend this patch in one or two months. Are you ok with it? Like Adrian said, there are pending patches (since 2013) which will brake compatibility with 1.3

The crystall ball[1] says that 4.2 will be released in August, that should be plenty of time for user space to catch up. So if you resend this end of April or so the patch should go to 4.2.

The 1.3.1 firmware will appear again shortly, and then a new subdirectory with per-version firmware images. So moving forward ath9k_htc can just check to see if the newer firmware is available, and fall back to the older firmware if needs be. If earlier kernels are booted then the linux-firmware install will still have htc_{7010,9271}.fw as 1.3.1, so those kernels will still work. Now - as for how long the tip of ath9k_htc development should work with older firmware - that's a good question. I think yes, waiting a couple more months before merging it in so userspace can catch up is fine.
