wireless-drivers-next patches for v5.9 Second set of patches for v5.9. These patches have not been build tested as much as normally because I'm on vacation right now. Hopefully this does not cause any regressions. mt76 has most of patches this time. Otherwise it's just smaller fixed and cleanups to other drivers. This pull request causes conflicts in four files in drivers/net/wireless/mediatek/mt76/mt7615/, here is how I fixed those: * usb.c: take the hunk which uses mt7663_usb_sdio_tx_*() functions * mt7615.h: remove either one of the duplicate (and identical) enum tx_pkt_queue_idx * mt7615.h: take the hunk which has mt7615_mutex_acquire/release() functions * main.c: take the hunk which uses mt7615_mutex_acquire/release() * mac.c: take the hunk which uses is_mmio Major changes: rtw88 * add support for ieee80211_ops::change_interface * add support for enabling and disabling beacon * add debugfs file for testing h2c mt76 * ARP filter offload for 7663 * runtime power management for 7663 * testmode support for mfg calibration * support for more channels
