[Cake] Airtime fairness patch merged upstream, and the Turris Omnia debloated

[Toke Høiland-Jørgensen]

The airtime fairness patch for ath9k has been accepted into the mainline
Linux kernel, and is queued to be merged for 4.11 (i.e. the next merge
window after the current 4.10 cycle completes).

The patch has also been accepted into LEDE and is currently in Felix'
staging tree at
https://git.lede-project.org/?p=lede/nbd/staging.git;a=summary - so if
nothing surprising shows up, it should make it into the regular LEDE
nightlies before too long :)


In related news, the Turris Omnia had the WiFi queue restructure patches
added in the latest update; and the ath10k chip it ships with seems to
have the required hardware support, so both WiFi devices in the Omnia
now have nicely debloated queues. They also switched to sqm-scripts
(from wondershaper that they shipped before), and added Cake :)
