Michael Chan says: ==================== bnxt_en: Implement new driver APIs to send FW messages The current driver APIs to send messages to the firmware allow only one outstanding message in flight. There is only one buffer for the firmware response for each firmware channel. To send a firmware message, all callers must take a mutex and it is released after the firmware response has been read. This scheme does not allow multiple firmware messages in flight. Firmware may take a long time to respond to some messages (e.g. NVRAM related ones) and this causes the mutex to be held for a long time, blocking other callers. This patchset intoduces the new driver APIs to address the above shortcomings. The new APIs are compatible with new and old firmware. But the new deferred firmware response mechanism will require newer firmware in order to allow multiple outstanding firmware commands. All callers are updated to use the new APIs. v2: Patch 4 and patch 9 updated to fix issues reported by test robot ==================== Signed-off-by: David S. Miller <davem@davemloft.net> |

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.
