The PR contains two patches:

  1. Fix issue: optical module temperature raising doesn't result in fan speed raising. Kernel thermal algorithm cannot detect optical module temperature changing. ASIC and gearbox has no issue, only optical module. (0058)
  2. Enable kernel detect the hottest thermal zone and perform thermal algorithm based on that. (0059)

How to fix?
Add a patch to init thermal trips for optical modules.

How to verify?
Raise temperature of optical modules and check fan speed is also raising.
