nfp: support IPsec offloading for NFP3800

2023-02-10T06:22:19+00:00

Add IPsec offloading support for NFP3800. Include data
plane and control plane.

Data plane: add IPsec packet process flow in NFP3800
datapath (NFDk).

Control plane: add an algorithm support distinction flow
in xfrm hook function xdo_dev_state_add(), as NFP3800 has
a different set of IPsec algorithm support.

This matches existing support for the NFP6000/NFP4000 and
their NFD3 datapath.

In addition, fixup the md_bytes calculation for NFD3 datapath
to make sure the two datapahts are keept in sync.

nfp: add DCB IEEE support

2023-01-14T05:40:01+00:00

Add basic DCB IEEE support. This includes support for ETS, max-rate,
and DSCP to user priority mapping.

DCB may be configured using iproute2's dcb command.
Example usage:
  dcb ets set dev $dev tc-tsa 0:ets 1:ets 2:ets 3:ets 4:ets 5:ets \
    6:ets 7:ets tc-bw 0:0 1:80 2:0 3:0 4:0 5:0 6:20 7:0
  dcb maxrate set dev $dev tc-maxrate 1:1000bit

And DCB configuration can be shown using:
  dcb ets show dev $dev
  dcb maxrate show dev $dev

nfp: add framework to support ipsec offloading

2022-11-21T08:51:36+00:00

A new metadata type and config structure are introduced to
interact with firmware to support ipsec offloading. This
feature relies on specific firmware that supports ipsec
encrypt/decrypt by advertising related capability bit.

The xfrm callbacks which interact with upper layer are
implemented in the following patch.

Based on initial work of Norm Bagley .

nfp: add support for NFDK data path

2022-03-21T13:21:17+00:00

Add new data path.  The TX is completely different, each packet
has multiple descriptor entries (between 2 and 32).  TX ring is
divided into blocks 32 descriptor, and descritors of one packet
can't cross block bounds. The RX side is the same for now.

ABI version 5 or later is required.  There is no support for
VLAN insertion on TX. XDP_TX action and AF_XDP zero-copy is not
implemented in NFDK path.

Changes to Jakub's work:
* Move statistics of hw_csum_tx after jumbo packet's segmentation.
* Set L3_CSUM flag to enable recaculating of L3 header checksum
in ipv4 case.
* Mark the case of TSO a packet with metadata prepended as
unsupported.

nfp: move the fast path code to separate files

2022-03-21T13:21:16+00:00

In preparation for support for a new datapath format move all
ring and fast path logic into separate files. It is basically
a verbatim move with some wrapping functions, no new structures
and functions added.

The current data path is called NFD3 from the initial version
of the driver ABI it used. The non-fast path, but ring related
functions are moved to nfp_net_dp.c file.

Changes to Jakub's work:
* Rebase on xsk related code.
* Split the patch, move the callback changes to next commit.

nfp: introduce dev_info static chip data

2022-03-12T07:10:22+00:00

In preparation for supporting new chip add a driver data structure
which will hold per-chip-version information such as register
offsets.

Plumb it through to the relevant functions (nfpcore and nfp_net).
For now only a very simple member holding chip names is added,
following commits will add more.

nfp: xsk: add AF_XDP zero-copy Rx and Tx support

2022-03-04T13:06:12+00:00

This patch adds zero-copy Rx and Tx support for AF_XDP sockets. It do so
by adding a separate NAPI poll function that is attached to a each
channel when the XSK socket is attached with XDP_SETUP_XSK_POOL, and
restored when the XSK socket is terminated, this is done per channel.

Support for XDP_TX is implemented and the XDP buffer can safely be moved
from the Rx to the Tx queue and correctly freed and returned to the XSK
pool once it's transmitted.

Note that when AF_XDP zero-copy is enabled, the XDP action XDP_PASS
will allocate a new buffer and copy the zero-copy frame prior
passing it to the kernel stack.

This patch is based on previous work by Jakub Kicinski.

nfp: add devlink param infrastructure

2019-09-10T16:29:27+00:00

Register devlink parameters for driver use. Subsequent patches will add
support for specific parameters.

In order to support devlink parameters, the management firmware needs to
be able to lookup and set hwinfo keys.
