There is a regular need in the kernel to provide a way to declare having a dynamically sized set of trailing elements in a structure. Kernel code should always use “flexible array members”[1] for these cases. The older style of one-element or zero-length arrays should no longer be used[2].

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).
