Compared to fixed payload packets, random payload packets have better
measured EVM under the same txpower. Our tests show EVM becomes at least
2-3 dB better in test cases with high rate and long tx length, which also
aligns the testing results to proprietary driver.

Originally, tx queued limit is set to 1000 to prevent from running out
of tx token. If a new testmode tx is triggered while the previous one
hasn't finished yet, we'll wait a period of time until tx_done equals to
tx_queued. Normally, current queued limit can finish in 10 seconds.
However, if ipg is configured to a larger value, less than 1000 packets
can be done in the default timeout period, which may lead to a crash
when a new testmode tx triggered.
To deal with this, make tx queued limit dynamically adjusted according
to ipg value.
