commit 57c942bc3bef0970f0b21f8e0998e76a900ea80d upstream.
When a tx_timeout fires, the PF attempts to recover by incrementally
resetting. First we try a PFR, then CORER and finally a GLOBR. If the
GLOBR fails, then we keep hitting the tx_timeout and incrementing the
recovery level and issuing dmesgs, which is both annoying to the user
and accomplishes nothing.
If the GLOBR fails, then we're pretty much totally hosed, and there's
not much else we can do to recover, so this makes it such that we just
kill the VSI and stop hitting the tx_timeout in such a case.

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.
