staying in carrier search (bool enable)

enable TRUE

1. Initialize a 2-element u16 array clip to 0xFFFF, 0xFFFF

2. if nphy_deaf_count is 0

   1. Call N PHY Classifier with 0, 0 as arguments and save as classifier_state

   2. Call N PHY Classifier with arguments 0x7, 0

   3. Call N PHY Clip Detection with arguments 0, clip_state

   4. Call N PHY Clip Detection with arguments 1, clip

3. Increase nphy_deaf_count

4. Call N PHY Reset CCA

disable (enable FALSE)

1. decrease nphy_deaf_count (probably a refcount?)

2. if it reached zero

   1. Call N PHY Classifier with 0x7, classifier_state as arguments

   2. Call N PHY Clip Detection with 1, clip_state as arguments
