> Subject: [PATCH v2 1/5] wifi: rtl8xxxu: Add central frequency offset tracking
>
> According to Realtek programmers, "to adjust oscillator to align
> central frequency of connected AP. Then, it can yield better
> performance." From commit fb8517f4fade ("rtw88: 8822c: add CFO
> tracking").
>
> The RTL8192CU and a version of RTL8723AU apparently don't have the
> ability to adjust the oscillator, so this doesn't apply to them.
>
> This also doesn't apply to the wifi + bluetooth combo chips (RTL8723AU
> and RTL8723BU) because the CFO tracking should only be done when
> bluetooth is disabled, and determining that looked complicated.
>
> That leaves only the RTL8192EU and RTL8188FU chips. I tested this with
> the latter.
