Add dev->tstats traffic accounting to netkit. The latter contains per-CPU RX and TX counters. The dev's TX counters are bumped upon pass/unspec as well as redirect verdicts, in other words, on everything except for drops. The dev's RX counters are bumped upon successful __netif_rx(), as well as from skb_do_redirect() (not part of this commit here). Using dev->lstats with having just a single packets/bytes counter and inferring one another's RX counters from the peer dev's lstats is not possible given skb_do_redirect() can also bump the device's stats.

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.
