The CCA threshold is not the same as the threshold for signal detection.
In many ways, 5k and 9k cards have a somewhat similar set of registers
to configure various aspects of detection sensitivity. Some of those are
set in the initvals, some are controlled by ANI.
The main issue is that the driver does not expose any convenient knobs
to control this.
