iwlwifi: mvm: ignore temperature updates in the RX statistics notification (57d7b6a4) · Commits · 戴 / test

If the firmware sends spontaneous DTS notfications with the temperature (indicated in a TLV), we can ignore the temperature we get in the RX statistics notifications. This prevents potentially handling the same temperature change twice. It also ignores notifications with temperature equal to 0 that happens from time to time. Signed-off-by:
