Currently the STOPPED IPA power flag is used to indicate that the transmit queue has been stopped. Previously this was used to avoid setting the STARTED flag unless the queue had already been stopped. It meant transmit queuing would be enabled on resume if it was stopped by the transmit path--and if so, it ensured it only got enabled once. We only stop the transmit queue in the transmit path. The STARTED flag has been removed, and it causes no real harm to enable transmits when they're already enabled. So we can get rid of the STOPPED flag and call netif_wake_queue() unconditionally. This makes the IPA power spinlock unnecessary, so it can be removed as well.

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.
