All uses of pnpid32_to_pnpid() were removed by
commit 25eb846189d2 ("PNP: add pnp_eisa_id_to_string()"),
so remove the declaration, too.

To repro this:
- Have 2 Wifi with the same bssid and pass on different band (2.4 and
5GHz)
- Enable 802.11r Fast Transaction with same mobility domain
- FT Protocol: FT over the Air
From a openwrt system issue the command (with the correct mac)
ubus call hostapd.wlan1 wnm_disassoc_imminent '{"addr":"28:C2:1F:xx:xx:xx"}'
Notice the log printing the errors.
The cause of this error has been investigated and we found that this is
related to the WiFi Fast Transaction feature. We observed that this is
triggered when the router tells the device to change band. In this case
the device first auth to the other band and then the disconnect path
from the prev band is triggered.
This is problematic with the current rhash implementation since the
addrs is used as key and the logic of "adding first, delete later"
conflicts with the rhash logic.
In fact peer addition will fail since the peer is already added and with
that fixed a peer deletion will cause unitended effect by removing the
peer just added.
Current solution to this is to add additional logic to the peer delete,
make sure we are deleting the correct peer taken from the rhash
table (and fallback to the peer list) and for the peer add logic delete
the peer entry for the rhash list before adding the new one (counting as
an error only when a peer with the same vlan_id is asked to be added).
With this change, a sta can correctly transition from 2.4GHz and 5GHZ
with no drop and no error are printed.

Check IEEE80211_TX_CTL_NO_CCK_RATE flag to avoid sending frames with
CCK rates in 2GHz band.
In TX flow, add IEEE80211_TX_CTL_NO_CCK_RATE flag to check and get its
lowest rate without CCK rates if the TX type is mgmt frames or data frames.
Besides, the decision of phy rate and retry rate in P2P mode are also
be handled.
In P2P GO mode, it should send beacon of no CCK rates in its frame rate.
Therefore, We add a condition to decide which rate is added to beacon
content.
Moreover, we avoid setting a mask of rates to be used for rate control
selection before and after connection in P2P mode.

This patch is needed to handle interrupts by the second VPE on the Lantiq
ARX100, xRX200, xRX300 and xRX330 SoCs. Switching some ICU interrupts to
the second VPE results in a hang. Currently, the vsmp_init_secondary()
function is responsible for enabling these interrupts. It only enables
Malta-specific interrupts (SW0, SW1, HW4 and HW5).
The MIPS core has 8 interrupts defined. On Lantiq SoCs, hardware
interrupts are wired to an ICU instance. Each VPE has an independent
instance of the ICU. The mapping of the ICU interrupts is shown below:
SW0(IP0) - IPI call,
SW1(IP1) - IPI resched,
HW0(IP2) - ICU 0-31,
HW1(IP3) - ICU 32-63,
HW2(IP4) - ICU 64-95,
HW3(IP5) - ICU 96-127,
HW4(IP6) - ICU 128-159,
HW5(IP7) - timer.
This patch enables all interrupt lines on the second VPE.
This problem affects multithreaded SoCs with a custom interrupt controller.
SOCs with 1004Kc core and newer use the MIPS GIC. At this point, I am aware
that the Realtek RTL839x and RTL930x SoCs may need a similar fix. In the
future, this may be replaced with some generic solution.
Tested on Lantiq xRX200.

A previous patch added a wrapper function to take a lock around
efx_mcdi_filter_table_remove(), but only changed EF10 VFs' method table
to call it. Change it in the PF method table too.

====================
net: ipa: another set of cleanups
This series contains another set of cleanups done in preparation for
an upcoming series that reworks how IPA registers and their fields
are defined.
The first replaces the use of u32_replace_bits() with a simple
logical AND operation in two places.
The second creates a new function to encapsulate some common code,
and renames another for consistency. The third restructures two
other functions that do similar things to make their similarity more
obvious.
The fourth defines the flag bits in a register using an enumerated
type. And the fifth updates "ipa_reg.h" so the values assigned to
enumerated type members are aligned consistently.
The last three encapsulate the code that assigns values to a few
registers into separate functions.

Update a few enumerated type definitions in "ipa_reg.h" so that the
values assigned to each member align on the same column. Where a
"TX" or "RX" (or both) comment is present, move that annotation into
a separate comment between the member name and its value.

The backward compatibility register (BCR) has a set of bit flags
that indicate ways in which the IPA hardware should operate in a
backward compatible way. The register is not supported starting
with IPA v4.5, and where it is supported, defined bits all have the
same numeric value.
Redefine these flags using an enumerated type, with each member's
value representing the bit position that encodes it in the BCR.
This replaces all of the single-bit field masks previously defined.

Both aggr_time_limit_encode() and hol_block_timer_encode() figure
out how to encode a millisecond time value so it can be programmed
into a register. Rearranging them a bit can make their similarity
more obvious, with both taking essentially the same form.
To do this:
- Return 0 immediately in aggr_time_limit_encode() if the
microseconds value supplied is zero.
- Reverse the test at top of aggr_time_limit_encode(), so we
compute and return the Qtime value in the "true" block,
and compute the result the old way otherwise.
- Open-code (and eliminate) hol_block_timer_qtime_encode() at the
top of hol_block_timer_encode() in the case we use Qtimer.

Create a new function ipa_qtime_val() which returns a value that
indicates what should be encoded for a register with a time field
expressed using Qtime. Use it to factor out common code in
aggr_time_limit_encoded() and hol_block_timer_qtime_val().
Rename aggr_time_limit_encoded() and hol_block_timer_qtime_val() so
their names are both verbs ending in "encode". Rename the "limit"
argument to the former to be "milliseconds" for consistency.

In two spots we use u32_replace_bits() to replace a set of bits in a
register while preserving the rest. Both of those cases just zero
the bits being replaced, and this can be done more simply without
using that function.

Alexey reported that the fraction of unknown filename instances in
kallsyms grew from ~0.3% to ~10% recently; Bill and Greg tracked it down
to assembler defined symbols, which regressed as a result of:
commit b8a9092330da ("Kbuild: do not emit debug info for assembly with LLVM_IAS=1")
In that commit, I allude to restoring debug info for assembler defined
symbols in a follow up patch, but it seems I forgot to do so in
commit a66049e2cf0e ("Kbuild: make DWARF version a choice")

Dmitrii, Fangrui, and Mashahiro note:
Before GCC 11 and Clang 12 -gsplit-dwarf implicitly uses -g2.
Fix CONFIG_DEBUG_INFO_SPLIT for gcc-11+ & clang-12+ which now need -g
specified in order for -gsplit-dwarf to work at all.
-gsplit-dwarf has been mutually exclusive with -g since support for
CONFIG_DEBUG_INFO_SPLIT was introduced in
commit 866ced950bcd ("kbuild: Support split debug info v4")
I don't think it ever needed to be.
