436396f26d nfp: support IPsec offloading for NFP3800
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.

f817554786 nfp: flower: add check for flower VF netdevs for get/set_eeprom
Move the nfp_net_get_port_mac_by_hwinfo() check to ahead in the
get/set_eeprom() functions to in order to check for a VF netdev, which
this function does not support.

It is debatable if this is a fix or an enhancement, and we have chosen
to go for the latter. It does address a problem introduced by
commit 74b4f1739d ("nfp: flower: change get/set_eeprom logic and enable for flower reps").
However, the ethtool->len == 0 check avoids the problem manifesting as a
run-time bug (NULL pointer dereference of app).

29744a10c5 net: flow_offload: provision conntrack info in ct_metadata
In order to offload connections in other states besides "established" the
driver offload callbacks need to have access to connection conntrack info.
Flow offload intermediate representation data structure already contains
that data encoded in 'cookie' field, so just reuse it in the drivers.

Reject offloading IP_CT_NEW connections for now by returning an error in
relevant driver callbacks based on value of ctinfo. Support for offloading
such connections will need to be added to the drivers afterwards.

66c0e13ad2 drivers: net: turn on XDP features
A summary of the flags being set for various drivers is given below.
Note that XDP_F_REDIRECT_TARGET and XDP_F_FRAG_TARGET are features
that can be turned off and on at runtime. This means that these flags
may be set and unset under RTNL lock protection by the driver. Hence,
READ_ONCE must be used by code loading the flag value.

Also, these flags are not used for synchronization against the availability
of XDP resources on a device. It is merely a hint, and hence the read
may race with the actual teardown of XDP resources on the device. This
may change in the future, e.g. operations taking a reference on the XDP
resources of the driver, and in turn inhibiting turning off this flag.
However, for now, it can only be used as a hint to check whether device
supports becoming a redirection target.

Turn 'hw-offload' feature flag on for:
 - netronome (nfp)
 - netdevsim.

Turn 'native' and 'zerocopy' features flags on for:
 - intel (i40e, ice, ixgbe, igc)
 - mellanox (mlx5).
 - stmmac
 - netronome (nfp)

Turn 'native' features flags on for:
 - amazon (ena)
 - broadcom (bnxt)
 - freescale (dpaa, dpaa2, enetc)
 - funeth
 - intel (igb)
 - marvell (mvneta, mvpp2, octeontx2)
 - mellanox (mlx4)
 - mtk_eth_soc
 - qlogic (qede)
 - sfc
 - socionext (netsec)
 - ti (cpsw)
 - tap
 - tsnep
 - veth
 - xen
 - virtio_net.

Turn 'basic' (tx, pass, aborted and drop) features flags on for:
 - netronome (nfp)
 - cavium (thunder)
 - hyperv.

Turn 'redirect_target' feature flag on for:
 - amanzon (ena)
 - broadcom (bnxt)
 - freescale (dpaa, dpaa2)
 - intel (i40e, ice, igb, ixgbe)
 - ti (cpsw)

ca3daf437d nfp: correct cleanup related to DCB resources
This patch corrects two oversights relating to releasing resources
and DCB initialisation.

1. If mapping of the dcbcfg_tbl area fails: an error should be
   propagated, allowing partial initialisation (probe) to be unwound.

2. Conversely, if where dcbcfg_tbl is successfully mapped: it should
   be unmapped in nfp_nic_dcb_clean() which is called via various error
   cleanup paths, and shutdown or removal of the PCIE device.

075935f0ae devlink: protect devlink param list by instance lock
Commit 1d18bb1a4d ("devlink: allow registering parameters after
the instance") as the subject implies introduced possibility to register
devlink params even for already registered devlink instance. This is a
bit problematic, as the consistency or params list was originally
secured by the fact it is static during devlink lifetime. So in order to
protect the params list, take devlink instance lock during the params
operations. Introduce unlocked function variants and use them in drivers
in locked context. Put lock assertions to appropriate places.

74b4f1739d nfp: flower: change get/set_eeprom logic and enable for flower reps
The changes in this patch are as follows:

- Alter the logic of get/set_eeprom functions to use the helper function
nfp_app_from_netdev() which handles differentiating between an nfp_net
and a nfp_repr. This allows us to get an agnostic backpointer to the
pdev.

- Enable the various eeprom commands by adding the 'get_eeprom_len',
'get_eeprom', 'set_eeprom' callbacks to the nfp_port_ethtool_ops struct.
This allows the eeprom commands to work on representor interfaces,
similar to a previous patch which added it to the vnics.
Currently these are being used to configure persistent MAC addresses for
the physical ports on the nfp.

5bee990f49 net: remove redundant config PCI dependency for some network driver configs
While reviewing dependencies in some Kconfig files, I noticed the redundant
dependency "depends on PCI && PCI_MSI". The config PCI_MSI has always,
since its introduction, been dependent on the config PCI. So, it is
sufficient to just depend on PCI_MSI, and know that the dependency on PCI
is implicitly implied.

Reduce the dependencies of some network driver configs.
No functional change and effective change of Kconfig dependendencies.

62f6eca5de xfrm: allow state packet offload mode
Allow users to configure xfrm states with packet offload mode.
The packet mode must be requested both for policy and state, and
such requires us to do not implement fallback.

We explicitly return an error if requested packet mode can't
be configured.

5c306de8f7 nfp: correct desc type when header dma len is 4096
When there's only one buffer to dma and its length is 4096, then
only one data descriptor is needed to carry it according to current
descriptor definition. So the descriptor type should be `simple`
instead of `gather`, the latter requires more than one descriptor,
otherwise it'll be dropped by application firmware.

226bf98055 net: devlink: let the core report the driver name instead of the drivers
The driver name is available in device_driver::name. Right now,
drivers still have to report this piece of information themselves in
their devlink_ops::info_get callback function.

In order to factorize code, make devlink_nl_info_fill() add the driver
name attribute.

Now that the core sets the driver name attribute, drivers are not
supposed to call devlink_info_driver_name_put() anymore. Remove
devlink_info_driver_name_put() and clean-up all the drivers using this
function in their callback.

A new command `SPCODE_READ_MEDIA` is added to read info from

The error is reflected in that it shows wrong splittable status of
port when executing "devlink port show".
The reason which leads the error is that the assigned operation of
splittable is just a simple negation operation of split and it does
not consider port lanes quantity. A splittable port should have
several lanes that can be split(lanes quantity > 1).
If without the judgement, it will show wrong message for some
firmware, such as 2x25G, 2x10G.

Extend the size of QSFP EEPROM for types SSF8436 and SFF8636
from 256 to 640 bytes in order to expose all the EEPROM pages by
ethtool.

For SFF-8636 and SFF-8436 specifications, the driver exposes
256 bytes of EEPROM data for ethtool's get_module_eeprom()
callback, resulting in "netlink error: Invalid argument" when
an EEPROM read with an offset larger than 256 bytes is attempted.

Changing the length enumerators to the _MAX_LEN
variants exposes all 640 bytes of the EEPROM allowing upper
pages 1, 2 and 3 to be read.
