Eric Joyner 1d4f8092bd ionic: Rate limit unknown xcvr type messages 
[ Upstream commit cdb1634de3 ]

Running ethtool repeatedly with a transceiver unknown to the driver or
firmware will cause the driver to spam the kernel logs with "unknown
xcvr type" messages which can distract from real issues; and this isn't
interesting information outside of debugging. Fix this by rate limiting
the output so that there are still notifications but not so many that
they flood the log.

Using dev_dbg_once() would reduce the number of messages further, but
this would miss the case where a different unknown transceiver type is
plugged in, and its status is requested.

Fixes: 4d03e00a21 ("ionic: Add initial ethtool support")

README 

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 reStructuredText markup notation.

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.
