Add infrastructure to maintain a pending list of HWRM commands awaiting completion and reduce the scope of the hwrm_cmd_lock mutex so that it protects only the request mailbox. The mailbox is free to use for one or more concurrent commands after receiving deferred response events. For uniformity and completeness, use the same pending list for collecting completions for commands that respond via a completion ring. These commands are only used for freeing rings and for IRQ test and we only support one such command in flight. Note deferred responses are also only supported on the main channel. The secondary channel (KONG) does not support deferred responses. Signed-off-by: Edwin Peer <edwin.peer@broadcom.com> Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

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.
