While loading a driver and changing the number of queues, I noticed this message in the kernel log: "[253489.070080] Number of in use tx queues changed invalidating tc mappings. Priority traffic classification disabled!" But I had no idea what interface was being talked about because this message used pr_warn(). After investigating, it appears we can use the netdev_* helpers already defined to create predictably formatted messages, and that already handle <unknown netdev> cases, in more of the messages in dev.c. After this change, this message (and others) will look like this: "[ 170.181093] ice 0000:3b:00.0 ens785f0: Number of in use tx queues changed invalidating tc mappings. Priority traffic classification disabled!" One goal here was not to change the message significantly from the original format so as to not break user's expectations, so I just changed messages that used pr_* and generally started with %s == dev->name.

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.
