If a TX hang occurs, we attempt to recover by incrementally resetting. If we're starved for CPU time, it's possible the reset doesn't actually complete (or even fire) before another tx_timeout fires causing us to fly through the different resets without actually doing them. This adds a bit to set and check if a timeout recovery is already pending and, if so, bail out of tx_timeout. The bit will get cleared at the end of i40e_rebuild when reset is complete.

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.
