octeontx2-pf: Add network driver for physical function
OcteonTX2 SOC's resource virtualization unit (RVU) supports
multiple physical and virtual functions. Each of the PF's
functionality is determined by what kind of resources are attached
to it. If NPA and NIX blocks are attached to a PF it can function
as a highly capable network device.
This patch series add a network driver for the PF. Initial set of
patches adds mailbox communication with admin function (RVU AF)
and configuration of queues. Followed by Rx and tx pkts NAPI
handler and then support for HW offloads like RSS, TSO, Rxhash etc.
Ethtool support to extract stats, config RSS, queue sizes, queue
count is also added.
Added documentation to give a high level overview of HW and
different drivers which will be upstreamed and how they interact.
Changes from v5:
* Fixed otx2_atomic64_add() non ARM64 fallback definition.
- Suggested by David Miller
Changes from v4:
* Replaced pci_set_dma_mask and pci_set_consistent_dma_mask
fn()s with dma_set_mask_and_coherent().
* Some additonal code cleanup.
* Fixed receive buffer segmnetation logic in otx2_alloc_rbuf()
* Removed all unused BIG_ENDIAN structure definitions.
* Removed unnecessary memory barriers
- Sugested by Jakub Kicinski
* Fixed mailbox initalization failure handling
* Removed unused function parameter in otx2_skb_add_frag()
- Suggested by Maciej Fijalkowski
Changes from v3:
* Fixed receive side scaling reinitialization during interface
DOWN and UP to retain user configured settings, if any.
* Removed driver version from ethtool.
* Fixed otx2_set_rss_hash_opts() to return error incase RSS is
not enabled.
- Sugested by Jakub Kicinski
Changes from v2:
* Removed frames, bytes, dropped packet stats from ethtool to avoid
duplication of same stats in netlink and ethtool.
- Sugested by Jakub Kicinski
* Removed number of channels and ringparam upper bound checking
in ethtool support.
* Fixed RSS hash option setting to reject unsupported config.
- Suggested by Michal Kubecek
Changes from v1:
* Made driver dependent on 64bit, to fix build errors related to
non availability of writeq/readq APIs for 32bit platforms.

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.
