ieee80211_tx_h_select_key() is performing a series of RCU dereferences, but rtw89_core_txq_push() is calling it (via ieee80211_tx_dequeue_ni()) without RCU read-side lock held; fix that.

To keep high sensitivity reaction, Bluetooth gaming controller will send packet very frequently, it will make WLAN performance very poor. To solve this situation, MIMO PS mechanism makes WLAN/BT own an antenna itself, WLAN quits 2SS performance but it can get a stable 1SS performance and Bluetooth gaming controller can keep sensitivity reaction at the same time.

The code validates the HE capability element size later, but slightly wrong, so use the new helper to do it right and only accept it if it has a good size. Link: https://lore.kernel.org/r/20220214172920.b5b06f264a61.I645ac1e2dc0ace223ef3e551cd5a71c88bd55e04@changeidSigned-off-by:

This element has a very dynamic structure, create a small helper function to validate its size. We're currently checking it in mac80211 in a conversion function, but that's actually slightly buggy.

Split 6G band into 8 sub-bands where indexes are from 0 to 7, i.e. RTW89_CH_6G_BAND_IDX[0-7]. Then, decide subband by both band and channel instead of just channel because conflicts between 5G channels and 6G channels. Moreover, add default case to the existing use of switch (subband).

BCM43454/6 is a variant of BCM4345 which is exactly identical to BCM4345/6, except the chip id is 0xa9be. This patch adds support for BCM43454/6 by handing it in the same way as BCM4345. Note: when loading some specific version of BCM4345 firmware, the chip id may become 0x4345. This is an expected behavior, and it will restore to 0xa9be after power cycle. Signed-off-by:
