Re: [PATCH] rtl8xxxu: Improve the A-MPDU retransmission rate with RTS/CTS protection

The A-MPDU retransmission rate is always high (> 20%) even in a very
clean environment. However, the vendor driver retransimission rate is
< 10% in the same test bed. The different is the vendor driver starts
the A-MPDU TXOP with initial RTS/CTS handshake which is observed in the
air capture and the TX descriptor. Since there's no related field in
TX descriptor to enable the L-SIG TXOP protection and the duration,
applying the RTS/CTS protection instead helps to lower the retransmission
rate from > 20% to ~12% in the same test setup.

You should have marked this as v2 because you submitted already before:

https://patchwork.kernel.org/project/linux-wireless/patch/20211129143953.369557-1-chris.chiu@canonical.com/

And include a list of changes between versions, more info in the wiki
below.
