So far the TX-FIFO is only used with a depth of 1, although the hardware offers a depth of 2. The workaround for the chips that are affected by erratum 6, i.e. EFF frames may be send as standard frames, is to re-send the EFF frame. This means the driver cannot queue the next frame for sending, as long ad the EFF frame has not been successfully send out. Introduce rkcanfd_get_effective_tx_free() that returns "0" space in the TX-FIFO if an EFF frame is pending and the actual free space in the TX-FIFO otherwise. Then replace rkcanfd_get_tx_free() with rkcanfd_get_effective_tx_free() everywhere.

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.
