Author: hselasky Date: Thu May 16 15:43:34 2019 New Revision: 347714 URL: https://svnweb.freebsd.org/changeset/base/347714 Log: MFC r347250: Add temperature warning event to log in mlx5core. Temperature warning event is sent by FW to indicate high temperature as detected by one of the sensors on the board. Add handling of this event by writing the numbers of the alert sensors to the kernel log.
