The kernel maintains three markers for the MDB dump:
1. The last bridge device from which the MDB was dumped.
2. The last MDB entry from which the MDB was dumped.
3. The last port-group entry that was dumped.
Add test cases for large scale MDB dump to make sure that all the
configured entries are dumped and that the markers are used correctly.
Specifically, create 2 bridges with 32 ports and add 256 MDB entries in
which all the ports are member of. Test that each bridge reports 8192
(256 * 32) permanent entries. Do that with IPv4, IPv6 and L2 MDB
entries.
On my system, MDB dump of the above is contained in about 50 netlink
messages.
Example output:
# ./bridge_mdb.sh

The purpose of the sequence generation counter in the netlink callback
is to identify if a multipart dump is consistent or not by calling
nl_dump_check_consistent() whenever a message is generated.
The function is not invoked by the MDB code, rendering the sequence
generation counter assignment pointless. Remove it.
Note that even if the function was invoked, we still could not
accurately determine if the dump is consistent or not, as there is no
sequence generation counter for MDB entries, unlike nexthop objects, for

net: ipa: prepare for GSI register updtaes
An upcoming series (or two) will convert the definitions of GSI
registers used by IPA so they use the "IPA reg" mechanism to specify
register offsets and their fields. This will simplify implementing
the fairly large number of changes required in GSI registers to
support more than 32 GSI channels (introduced in IPA v5.0).
A few minor problems and inconsistencies were found, and they're
fixed here. The last three patches in this series change the
"ipa_reg" code to separate the IPA-specific part (the base virtual
address, basically) from the generic register part, and the now-
generic code is renamed to use just "reg_" or "REG_" as a prefix
rather than "ipa_reg" or "IPA_REG_".

IPA register definitions have evolved with each new version. The
changes required to support more than 32 endpoints in IPA v5.0 made
it best to define a unified mechanism for defining registers and
their fields.
GSI register definitions, meanwhile, have remained fairly stable.
And even as the total number of IPA endpoints goes beyond 32, the
number of GSI channels on a given EE that underly endpoints still
remains 32 or less.
Despite that, GSI v3.0 (which is used with IPA v5.0) extends the
number of channels (and events) it supports to be about 256, and as
a result, many GSI register definitions must change significantly.
To address this, we'll use the same "ipa_reg" mechanism to define
the GSI registers.
As a first step in generalizing the "ipa_reg" to also support GSI
registers, isolate the definitions of the "ipa_reg" and "ipa_regs"
structure types (and some supporting macros) into a new header file,
and remove the "ipa_" and "IPA_" from symbol names.
Separate the IPA register ID validity checking from the generic
check that a register ID is in range. Aside from that, this is
intended to have no functional effect on the code.

There are seven GSI interrupt types that can be signaled by a single
GSI IRQ. These are represented in a bitmask, and the gsi_irq_type_id
enumerated type defines what each bit position represents.
Similarly, the global and general GSI interrupt types each has a set
of conditions it signals, and both types have an enumerated type
that defines which bit that represents each condition.
When used, these enumerated values are passed as an argument to BIT()
in *all* cases. So clean up the code a little bit by defining the
enumerated type values as one-bit masks rather than bit positions.

Merge tag 'rxrpc-next-20230208' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-fs
David Howells says:
====================
rxrpc development
Here are some miscellaneous changes for rxrpc:
(1) Use consume_skb() rather than kfree_skb_reason().
(2) Fix unnecessary waking when poking and already-poked call.
(3) Add ack.rwind to the rxrpc_tx_ack tracepoint as this indicates how
many incoming DATA packets we're telling the peer that we are
currently willing to accept on this call.
(4) Reduce duplicate ACK transmission. We send ACKs to let the peer know
that we're increasing the receive window (ack.rwind) as we consume
packets locally. Normal ACK transmission is triggered in three places
and that leads to duplicates being sent.

Use string_is_terminated() helper instead of cpecific memchr() call.
This shows better the intention of the call.

Move string_is_valid() to the header for wider use.
While at it, rename to string_is_terminated() to be
precise about its semantics.

Add support for cable diagnostics in lan8841 PHY. It has the same
registers layout as lan8814 PHY, therefore reuse the functionality.

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.

Paolo Abeni says:
====================
net: introduce rps_default_mask
Real-time setups try hard to ensure proper isolation between time
critical applications and e.g. network processing performed by the
network stack in softirq and RPS is used to move the softirq
activity away from the isolated core.
If the network configuration is dynamic, with netns and devices
routinely created at run-time, enforcing the correct RPS setting
on each newly created device allowing to transient bad configuration
became complex.
Additionally, when multi-queue devices are involved, configuring rps
in user-space on each queue easily becomes very expensive, e.g.
some setups use veths with per cpu queues.
These series try to address the above, introducing a new
sysctl knob: rps_default_mask. The new sysctl entry allows
configuring a netns-wide RPS mask, to be enforced since receive
queue creation time without any fourther per device configuration
required.
Additionally, a simple self-test is introduced to check the
rps_default_mask behavior.

If RPS is enabled, this allows configuring a default rps
mask, which is effective since receive queue creation time.
A default RPS mask allows the system admin to ensure proper
isolation, avoiding races at network namespace or device
creation time.
The default RPS mask is initially empty, and can be
modified via a newly added sysctl entry.

Will be used by the following patch to avoid code
duplication. No functional changes intended.
The only difference is that now flow_limit_cpu_sysctl() will
always compute the flow limit mask on each read operation,
even when read() will not return any byte to user-space.
Note that the new helper is placed under a new #ifdef at
the file start to better fit the usage in the later patch

Antenna gain is defined as the antenna’s ability to
increase the Tx power in a given direction. Intel
is certifying its products with fixed reference
antenna peak gain values (3/5dBi). The feature takes
into account the actual antenna gain, and increases
output power values, which results in a performance
improvement.
After firmware download is completed, driver reads from
ACPI table and configures PPAG as required. ACPI table
entry for PPAG is defined as below.
Name (PPAG, Package (0x02)
{
0x00000001,
Package (0x02)
{
0x00000012, /* Bluetooth Domain */
0x00000001 /* 1 - Enable PPAG, 0 - Disable PPAG */
}
