Rahul Lakkireddy 69422a7e5d cxgb4: fix EOTID leak when disabling TC-MQPRIO offload
Under heavy load, the EOTID termination FLOWC request fails to get
enqueued to the end of the Tx ring due to lack of credits. This
results in EOTID leak.

When disabling TC-MQPRIO offload, the link is already brought down
to cleanup EOTIDs. So, flush any pending enqueued skbs that can't be
sent outside the wire, to make room for FLOWC request. Also, move the
FLOWC descriptor consumption logic closer to when the FLOWC request is
actually posted to hardware.

README

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.
