Some of the chip-specific hw_start functions set bit TXCFG_AUTO_FIFO
in register TxConfig. The original patch changed the order of some
calls resulting in these changes being overwritten by
rtl_set_tx_config_registers() in rtl_hw_start(). This eventually
resulted in network stalls especially under high load.
Analyzing the chip-specific hw_start functions all chip version from
34, with the exception of version 39, need this bit set.
This patch moves setting this bit to rtl_set_tx_config_registers().

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
