[ Upstream commit0cea0e1148] The RX power read from the SFP uses units of 0.1uW. This must be scaled to units of uW for HWMON. This requires a divide by 10, not the current 100. With this change in place, sensors(1) and ethtool -m agree: sff2-isa-0000 Adapter: ISA adapter in0: +3.23 V temp1: +33.1 C power1: 270.00 uW power2: 200.00 uW curr1: +0.01 A Laser output power : 0.2743 mW / -5.62 dBm Receiver signal average optical power : 0.2014 mW / -6.96 dBm Reported-by: chris.healy@zii.aero Signed-off-by: Andrew Lunn <andrew@lunn.ch> Fixes:1323061a01("net: phy: sfp: Add HWMON support for module sensors") Signed-off-by: David S.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
