Add support for the perf_event_output family of helpers. The implementation on the NFP will not match the host code exactly. The state of the host map and rings is unknown to the device, hence device can't return errors when rings are not installed. The device simply packs the data into a firmware notification message and sends it over to the host, returning success to the program. There is no notion of a host CPU on the device when packets are being processed. Device will only offload programs which set BPF_F_CURRENT_CPU. Still, if map index doesn't match CPU no error will be returned (see above). Dropped/lost firmware notification messages will not cause "lost events" event on the perf ring, they are only visible via device error counters. Firmware notification messages may also get reordered in respect to the packets which caused their generation.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
