Retry Chain table is implemented here. Note this Retry Chain is different from Legacy Minstrel.

Try | LOOKAROUND RATE | NORMAL RATE

1 | Random rate | Best throughput 2 | Next best throughput | Next best throughput 3 | Best probability | Best probability

Note: For clarity, multiple blocks of if's and else's are used Following implementation in Linux, in MinstrelHT Lowest baserate is not used. Explanation can be found here: http://marc.info/?l=linux-wireless&m=144602778611966&w=2
