The netif_* functions are used by the driver to log events into the kernel ring (dmesg) similar to the netdev_* ones. Unlike the latter, the netif_* function family allow the user to choose what events get logged using ethtool: sudo ethtool -s [interface] msglvl [msg_type] on By default the events which get logged are slow-path related and aren't printed often (e.g. interface up related prints). This patch removes the NETIF_MSG_TX_DONE type (called every TX completion polling) from the defaults and adds NETIF_MSG_IFDOWN instead as it makes more sensible defaults. This patch also transforms ena_down() print from netif_info into netif_dbg (same as the analogue print in ena_up()) as it suits it better.

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.
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.
