tg3 has a spin lock protecting most of the config,
switch to taking netdev_lock() explicitly on enable/start
paths. Disable/stop paths seem to not be under the spin
lock (since napi_disable() already needs to sleep),
so leave that side as is.
tg3_restart_hw() releases and re-takes the spin lock,
we need to do the same because dev_close() needs to
take netdev_lock().
Fixes: 413f0271f3 ("net: protect NAPI enablement with netdev_lock()")

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.
