- in HT mode
-
-Long/short preamble selection cannot be sampled separately, since it
-depends on the BSS state. Because of that, sampling attempts to
-currently not used preamble modes are not counted in the statistics,
-which leads to CCK rates being sampled too often.
-
-Fix statistics accounting for long/short preamble by increasing the
-index where necessary.
-Fix excessive CCK rate sampling by dropping unsupported sample attempts.
-
-This improves throughput on 2.4 GHz channels
