commit 2f228d364da95ab58f63a3fedc00d5b2b7db16ab upstream.
Structs rx_desc_92d and rx_fwinfo_92d will not work for big endian
systems.
Delete rx_desc_92d because it's big and barely used, and instead use
the get_rx_desc_rxmcs and get_rx_desc_rxht functions, which work on big
endian systems too.
Fix rx_fwinfo_92d by duplicating four of its members in the correct
order.
Tested only with RTL8192DU, which will use the same code.
Tested only on a little endian system.

commit a7c0f48410f546772ac94a0f7b7291a15c4fc173 upstream.
Some (all?) management frames are incorrectly reported to mac80211 as
decrypted when actually the hardware did not decrypt them. This results
in speeds 3-5 times lower than expected, 20-30 Mbps instead of 100
Mbps.
Fix this by checking the encryption type field of the RX descriptor.
rtw88 does the same thing.
This fix was tested only with rtl8192du, which will use the same code.

[ Upstream commit b05897ca8c821a16ac03850c4704fe460b3f21a0 ]
Don't populate arrays the stack but instead make them static const. Replace
array channel_info with channel_all since it contains the same data as
channel_all. Makes object code smaller by 961 bytes.
