Nathan Rossi 4ff476b881 net: ethernet: aquantia: Handle error cleanup of start on open
[ Upstream commit 8a28af7a3e85ddf358f8c41e401a33002f7a9587 ]

The aq_nic_start function can fail in a variety of cases which leaves
the device in broken state.

An example case where the start function fails is the
request_threaded_irq which can be interrupted, resulting in a EINTR
result. This can be manually triggered by bringing the link up (e.g. ip
link set up) and triggering a SIGINT on the initiating process (e.g.
Ctrl+C). This would put the device into a half configured state.
Subsequently bringing the link up again would cause the napi_enable to
BUG.

In order to correctly clean up the failed attempt to start a device call
aq_nic_stop.

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.
