wait QSFP rest and BMC |
…reporting This commit introduces a comprehensive thermal management policy for transceivers (XCVR) and integrates it with the BMC. Key changes include: - build: Add `ipmitool` to base packages. - sys: Introduce `bmc_thermal_data` sysfs attribute to send thermal data (temperature and port number) to the BMC via IPMI cmd 0x13. - onlp: Implement temperature and high-alarm getters for SFF-8472, SFF-8436, and CMIS compatible modules. - onlp: Add Over-Temperature Protection (OTP) logic to disable e-fuse for SFPs or reset QSFPs when critical temperatures are exceeded. - onlp: Spawn a dedicated thermal policy `pthread`, triggered during fan management, to evaluate OTP conditions and sync the highest transceiver temperature to the BMC.
