Thanks Olivers suggestion for machine gun noise

1.      Check if using G.729 has higher such noise chance than G.711.

2.      When use G.711, put pockets by using iperf or smartbit to check if machine gun noise is more serious.

3.      What is your WiFi driver implement method, work queue or tasklet?

4.      Would it be possible to use one version that is only can make call, without all other drivers to verify?

In parallel, we will implement a code to check MHz utilization and release to you tomorrow.
