    -    wifi: rt2800: report the MCS16 to MCS8 fallback of RT3593 in TX status
    +    wifi: rt2800: make MCS 16 fall back to MCS 8 on devices with 3 TX chains
     
    -    The RT3593 retry chain is now MCS 16 to MCS 8, skipping 7 MCS
    -    rates in between. Reflect that in the retry calculation code.
    +    MCS 15 has worse reliability than MCS 16, since 16 and above
    +    are 3 stream rates, and 15 is the top of the 2 stream rates.
    +    Falling back from MCS 16 to MCS 15 does not make sense, so
    +    make the fallback to MCS 8 on all devices with 3 TX chains,
    +    like the Ralink driver does.
    +
    +    The retry chain is now MCS 16 to MCS 8, skipping 7 MCS rates
    +    in between. Reflect that in the retry calculation code. This
    +    also fixes the retry count on RT3883, which already used this
    +    fallback.
