Mario Limonciello 3cf31b1a9e e1000e: bump up timeout to wait when ME un-configures ULP mode
Per guidance from Intel ethernet architecture team, it may take
up to 1 second for unconfiguring ULP mode.

However in practice this seems to be taking up to 2 seconds on
some Lenovo machines.  Detect scenarios that take more than 1 second
but less than 2.5 seconds and emit a warning on resume for those
scenarios.

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.
