wifi: mt76: add flexible polling wait-interval support

2023-05-11T14:11:16Z

[ Upstream commit 35effe6c0c24adcf0f732bb1c3d75573d4c88e63 ] The default waiting unit is 10ms and the value is too much for data path related control. Provide a new API mt76_poll_msec_tick() to support different cases, such as 1ms polling waiting kick.

wifi: mt76: do not run mt76_unregister_device() on unregistered hw

2023-03-30T10:50:50Z

[ Upstream commit 41130c32f3a18fcc930316da17f3a5f3bc326aa1 ] Trying to probe a mt7921e pci card without firmware results in a successful probe where ieee80211_register_hw hasn't been called. When removing the driver, ieee802111_unregister_hw is called unconditionally leading to a kernel NULL pointer dereference. Fix the issue running mt76_unregister_device routine just for registered hw.

wifi: mt76: fix coverity overrun-call in mt76_get_txpower()

Revert "mt76: use IEEE80211_OFFLOAD_ENCAP_ENABLED instead of MT_DRV_AMSDU_OFFLOAD"

2022-12-01T16:29:12Z

This reverts commit f17f4864504d754bcbf31e4c89412cdf9946c409 and adds the MT_DRV_AMSDU_OFFLOAD flag for MT7921 USB/SDIO The reverted commit significantly decreases performance when running a test where two MT7915 radios have 16 station vdevs each, configured for AC mode, and transmitting UDP traffic to AP.
