Bryan Whitehead dd9d9f5907 lan743x: Fix RX Kernel Panic
It has been noticed that running the speed test at
www.speedtest.net occasionally causes a kernel panic.

Investigation revealed that under this test RX buffer allocation
sometimes fails and returns NULL. But the lan743x driver did
not handle this case.

This patch fixes this issue by attempting to allocate a buffer
before sending the new rx packet to the OS. If the allocation
fails then the new rx packet is dropped and the existing buffer
is reused in the DMA ring.

Updates for v2:
    Additional 2 locations where allocation was not checked,
        has been changed to reuse existing buffer.

Fixes: 23f0703c12 ("lan743x: Add main source files for new lan743x driver")

README

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.
