Enable previously excluded xdp feature flag for NFD3 devices. This
feature flag is required in order to bind nfp interfaces to an xdp
socket and the nfp driver does in fact support the feature.

When physical ports are reset (either through link failure or manually
toggled down and up again) that are slaved to a Linux bond with a tunnel
endpoint IP address on the bond device, not all tunnel packets arriving
on the bond port are decapped as expected.
The bond dev assigns the same MAC address to itself and each of its
slaves. When toggling a slave device, the same MAC address is therefore
offloaded to the NFP multiple times with different indexes.
The issue only occurs when re-adding the shared mac. The
nfp_tunnel_add_shared_mac() function has a conditional check early on
that checks if a mac entry already exists and if that mac entry is
global: (entry && nfp_tunnel_is_mac_idx_global(entry->index)). In the
case of a bonded device (For example br-ex), the mac index is obtained,
and no new index is assigned.
We therefore modify the conditional in nfp_tunnel_add_shared_mac() to
check if the port belongs to the LAG along with the existing checks to
prevent a new global mac index from being re-assigned to the slave port.

The 1st and 2nd expansion BAR configuration registers are configured,
when the driver starts up, in variables 'barcfg_msix_general' and
'barcfg_msix_xpb', respectively. The 'LengthSelect' field is ORed in
from bit 0, which is incorrect. The 'LengthSelect' field should
start from bit 27.
This has largely gone un-noticed because
NFP_PCIE_BAR_PCIE2CPP_LengthSelect_32BIT happens to be 0.

The nfp driver will merge the tp source port and tp destination port
into one dword which the offset must be zero to do hardware offload.
However, the mangle action for the tp source port and tp destination
port is separated for tc ct action. Modify the mangle action for the
FLOW_ACT_MANGLE_HDR_TYPE_TCP and FLOW_ACT_MANGLE_HDR_TYPE_UDP to
satisfy the nfp driver offload check for the tp port.
The mangle action provides a 4B value for source, and a 4B value for
the destination, but only 2B of each contains the useful information.
For offload the 2B of each is combined into a single 4B word. Since the
incoming mask for the source is '0xFFFF<mask>' the shift-left will
throw away the 0xFFFF part. When this gets combined together in the
offload it will clear the destination field. Fix this by setting the
lower bits back to 0xFFFF, effectively doing a rotate-left operation on
the mask.

The nfp offload flow pay will not allocate a mask id when the out port
is openvswitch internal port. This is because these flows are used to
configure the pre_tun table and are never actually send to the firmware
as an add-flow message. When a tc rule which action contains ct and
the post ct entry's out port is openvswitch internal port, the merge
offload flow pay with the wrong mask id of 0 will be send to the
firmware. Actually, the nfp can not support hardware offload for this
situation, so return EOPNOTSUPP.

ida_alloc() and ida_free() should be preferred to the deprecated
ida_simple_get() and ida_simple_remove().
This is less verbose.
Note that the upper bound of ida_alloc_range() is inclusive while the one
of ida_simple_get() was exclusive.
So NFP_FL_LAG_GROUP_MAX has been decreased by 1. It now better watch the
comment stating that "1 to 31 are valid".
The only other user of NFP_FL_LAG_GROUP_MAX has been updated accordingly in
nfp_fl_lag_put_unprocessed().

The get/set_rxfh ethtool ops currently takes the rxfh (RSS) parameters
as direct function arguments. This will force us to change the API (and
all drivers' functions) every time some new parameters are added.
This is part 1/2 of the fix, as suggested in [1]:
- First simplify the code by always providing a pointer to all params
(indir, key and func); the fact that some of them may be NULL seems
like a weird historic thing or a premature optimization.
It will simplify the drivers if all pointers are always present.
- Then make the functions take a dev pointer, and a pointer to a
single struct wrapping all arguments. The set_* should also take
an extack.

This patch converts some basic cases of ethtool_sprintf() to
ethtool_puts().
The conversions are used in cases where ethtool_sprintf() was being used
with just two arguments:
| ethtool_sprintf(&data, buffer[i].name);
or when it's used with format string: "%s"
| ethtool_sprintf(&data, "%s", buffer[i].name);
which both now become:
| ethtool_puts(&data, buffer[i].name);

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.
We expect res->name to be NUL-terminated based on its usage with format
strings:
| dev_err(cpp->dev.parent, "Dangling area: %d:%d:%d:0x%0llx-0x%0llx%s%s\n",
| NFP_CPP_ID_TARGET_of(res->cpp_id),
| NFP_CPP_ID_ACTION_of(res->cpp_id),
| NFP_CPP_ID_TOKEN_of(res->cpp_id),
| res->start, res->end,
| res->name ? " " : "",
| res->name ? res->name : "");
... and with strcmp()
| if (!strcmp(res->name, NFP_RESOURCE_TBL_NAME)) {
Moreover, NUL-padding is not required as `res` is already
zero-allocated:
| res = kzalloc(sizeof(*res), GFP_KERNEL);
Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.
Let's also opt to use the more idiomatic strscpy() usage of (dest, src,
sizeof(dest)) rather than (dest, src, SOME_LEN).
Typically the pattern of 1) allocate memory for string, 2) copy string
into freshly-allocated memory is a candidate for kmemdup_nul() but in
this case we are allocating the entirety of the `res` struct and that
should stay as is. As mentioned above, simple 1:1 replacement of strncpy
-> strscpy :)

When there are CT table entries, and you rmmod nfp, the following
events can happen:
task1：
nfp_net_pci_remove
↓
nfp_flower_stop->(asynchronous)tcf_ct_flow_table_cleanup_work(3)
↓
nfp_zone_table_entry_destroy(1)
task2：
nfp_fl_ct_handle_nft_flow(2)
When the execution order is (1)->(2)->(3), it will crash. Therefore, in
the function nfp_fl_ct_del_flow, nf_flow_table_offload_del_cb needs to
be executed synchronously.
At the same time, in order to solve the deadlock problem and the problem
of rtnl_lock sometimes failing, replace rtnl_lock with the private
nfp_fl_lock.

The dev_rx_discards counter will increment by one when an interface is
toggled up and down. The main reason is that the driver first sends a
`NFP_NET_CFG_CTRL_ENABLE` configuration packet to the NIC to perform port
initialisation when an interface is set up. But there is a race between
physical link up and free list queue initialization which may lead to the
configuration packet being discarded.
To address this problem a new bit NFP_NET_CFG_CTRL_FREELIST_EN is added to
perform free list initialisation on the NIC. The FREELIST_EN should be sent
in advance to initialize free list queue. When a port is set to down,
FREELIST_EN should be sent after CTRL_ENABLE to avoid packet discards.

All callers of tls_is_sk_tx_device_offloaded() currently do
an equivalent of:
if (skb->sk && tls_is_skb_tx_device_offloaded(skb->sk))
Have the helper accept skb and do the skb->sk check locally.
Two drivers have local static inlines with similar wrappers
already.
While at it change the ifdef condition to TLS_DEVICE.
Only TLS_DEVICE selects SOCK_VALIDATE_XMIT, so the two are
equivalent. This makes removing the duplicated IS_ENABLED()

Add layer 4 RSS hashing on UDP traffic to allow for the
utilization of multiple queues for multiple connections on
the same IP address.
Previously, since the introduction of the driver, RSS hashing
was only performed on the source and destination IP addresses
of UDP packets thereby limiting UDP traffic to a single queue
for multiple connections on the same IP address. The transport
layer is now included in RSS hashing for UDP traffic, which
was not previously the case. The reason behind the previous
limitation is unclear - either a historic limitation of the
NFP device, or an oversight.

The patch corrects the NFP_NET_MAX_DSCP definition in the main.h file.
The incorrect definition result DSCP bits not being mapped properly when
DCB is set. When NFP_NET_MAX_DSCP was defined as 4, the next 60 DSCP
bits failed to be set.

Avoid reading link modes from management firmware every time when
`ethtool_get_link_ksettings` is called, only communicate with
management firmware when necessary like we do for eth_table info.
This change can ease the situation that when large number of vlan
sub-interfaces are created and their information is requested by
some monitoring process like PCP [1] through ethool ioctl frequently.

There are two pointers in struct xfrm_dev_offload, *dev, *real_dev.
The *dev points whether bonding interface or real interface, if
bonding IPsec offload is used, it points bonding interface; if not,
it points real interface. And *real_dev always points real interface.
So nfp should always use real_dev instead of dev.
Prior to this change the system becomes unresponsive when offloading
IPsec for a device which is a lower device to a bonding device.

`dev_port` is used to differentiate devices that instantiate from
the same function, which is the case in most of NFP NICs.
In some customized scenario, `dev_port` is used to rename netdev
instead of `phys_port_name`. Example rules using `dev_port`:
SUBSYSTEM=="net", ACTION=="add", KERNELS=="0000:e1:00.0", ATTR{dev_port}=="0", NAME:="ens8np0"
SUBSYSTEM=="net", ACTION=="add", KERNELS=="0000:e1:00.0", ATTR{dev_port}=="1", NAME:="ens8np1"
To take port split case into account, here we initialize `dev_port`
according to the port sequence in eth_table from management firmware
instead of using port label id directly. And management firmware
makes sure that port sequence matches its label id.

If goto_chain action present in the post ct flow rule, merge flow rules
in this ct-zone, create a new pre_ct entry as the pre ct flow rule of
next ct-zone, but do not offload merged flow rules to firmware. Repeat
the process in the next ct-zone until no goto_chain action present in
the post ct flow rule in a certain ct-zone, merged all the flow rules.
Offload to firmware finally.

The chain_index has different means in pre ct entry and post ct entry.
In pre ct entry, it means chain index, but in post ct entry, it means
goto chain index, it is confused.
chain_index and goto_chain_index may be present in one flow rule, It
cannot be distinguished by one field chain_index, both chain_index
and goto_chain_index are required in the follow-up patch to support
multiple ct zones
Another field goto_chain_index is added to record the goto chain index.
If no goto action in post ct entry, goto_chain_index is 0.

'ct_clear' action only or no ct action is supported for 'post_ct_flow'.
But in scenario of multiple ct zones, one non 'ct_clear' ct action or
more ct actions, including 'ct_clear action', may be present in one flow
rule. If ct state match key is 'ct_established', the flow rule is still
expected to be classified as 'post_ct_flow'. Check ct status first in
function "is_post_ct_flow" to achieve this.

In the scenario of multiple ct zones, ct state key match and ct action
is present in one flow rule, the flow rule is classified to post_ct_flow
in design.
There is no ct state key match for pre ct flow, the judging condition
is added to function "is_pre_ct_flow".
Chain_index is another field for judging which flows are pre ct flow
If chain_index not 0, the flow is not pre ct flow.

The csum flag of IPsec packet are set repeatedly. Therefore, the csum
flag set of IPsec and non-IPsec packet need to be distinguished.
As the ipv6 header does not have a csum field, so l3-csum flag is not
