USB transport adds significant latency to H2C/C2H round-trips used
by RF calibration. The existing timeout values were designed for PCIe
and are too tight for USB, causing "failed to wait RF DACK",
"failed to wait RF TSSI" and similar errors on USB adapters.
Apply a 4x timeout multiplier when the device uses USB transport.
The multiplier is applied in rtw89_phy_rfk_report_wait() so all
calibrations benefit without changing any call sites or PCIe
timeout values.
The 4x multiplier was chosen based on measured data from two
independent testers (RTL8922AU, 6GHz MLO and 2.4/5GHz):
Calibration PCIe timeout Max measured (USB) 4x timeout
PRE_NTFY 5ms 1ms 20ms
DACK 58ms 72ms 232ms
RX_DCK 128ms 374ms 512ms
TSSI normal 20ms 24ms 80ms
TSSI scan 6ms 14ms 24ms
TXGAPK 54ms 18ms 216ms
IQK 84ms 53ms 336ms
DPK 34ms 30ms 136ms
Tested with RTL8922AU on 6GHz MLO (5GHz + 6GHz simultaneous):
25 connect/disconnect cycles with zero failures.
The 4x multiplier was also verified under adverse host conditions
on 5GHz. 5 cycles per scenario, stress-ng as the load generator,
max observed time per calibration:
Calibration PCIe 4x Baseline CPU stress Mem stress Combined
PRE_NTFY 5 20 0 0 0 1
DACK 58 232 71 (!) 71 (!) 71 (!) 71 (!)
RX_DCK 128 512 23 22 22 23
IQK 84 336 53 53 53 53
DPK 34 136 23 23 26 23
TSSI 20 80 6 9 14 9
TXGAPK 54 216 16 16 16 16
Legend: (!) = exceeds PCIe budget but within 4x budget.
Two observations from that matrix:
1. DACK exceeds the stock PCIe budget (58ms) in baseline on 5GHz
on this hardware. Without the 4x multiplier, DACK fails
-ETIMEDOUT deterministically on every connect, no stress
needed. This is the condition the patch addresses.
2. Calibration times appear dominated by USB transport round-trip
latency rather than host load, though hardware and external
component factors may also contribute. DACK stays at 71ms
across all four scenarios. Host-side stress has essentially
zero effect on observed calibration duration. Bumping the
multiplier above 4x would not address a failure mode that
this stress matrix produces.

It was recently reported that rtw_fw_adaptivity_result()
in fw.c dereferences rtwdev->chip->edcca_th without
a NULL check. The issue is that devices with the
8821CE chip don't define edcca_th in their chip
info. As a result, when rtw_fw_adaptivity_result()
tries to dereference it, the kernel triggers an oops.
Add a NULL check for edcca_th before dereferencing
it in rtw_fw_adaptivity_result() in fw.c. Placing
the check at the function entry avoids logging any
garbage values.
This change does not address the root cause for
this behavior, but it prevents the NULL dereference
and the resulting oops while a more permanent solution
is developed.
Tested on a 8822CE chip which defines edcca_th, so
this issue is not present on it, but it still uses
this driver and I can verify there are no regressions.

Jouni reported that certain sequences of tests caused some
WDS tests to fail after applying the upcoming hwsim changes
for NAN. I bisected that down to converting hwsim to TXQs,
and after a long debug session found that the 4-addr NDP was
getting dropped, because it goes out via a (management) TXQ
and is a data frame.
It's unclear to me now why this only happens in some test
sequences (e.g. "sigma_dut_sae_h2e_ap_loop ap_wds_sta" and
"sigma_dut_eap_ttls_all_akm_suites ap_wds_sta_open"), maybe
that affects timing and the frame is otherwise delayed in
some way.
Correct the check to only drop frames that actually carry
data, not NDPs.

When a (link) station connected to an AP interface is not
capable of EHT, it's possible that the AP interface is in
160 MHz but the HE channel is narrower, e.g. when EHT has
puncturing. In this case, the code doesn't correctly set
the STAs bandwidth, the station might be capable of using
160 MHz, but it can't use EHT 160 MHz with puncturing, so
it must be set to narrower.
Track the AP's 'he_and_lower_bw' bandwidth, use that when
calculating the maximum bandwidth to transmit to/from any
station not capable of EHT, and update all stations and
the chanctx min_def when it changes.

The per-STA bandwidth handling is completely confusing, given
the function names etc.
Move everything to sta_info.c and rename the functions to
accurately reflect what they return:
- ieee80211_sta_bw_capability()
- ieee80211_sta_current_bw() can return the appropriate
bandwidth in the desired direction (a new enum)
At any given time, the bandwidth with which we expect to receive
frames from a station may differ from the bandwidth with which
we may transmit frames to the station; this will happen either
during RX OMI negotiation, or for a long time if the station
used an HT Notify Channel Width frame. We also implement the
(VHT) Operating Mode Notification as an asymmetric setting, even
if the spec would seem to imply it could be symmetric.
Also rename the 'cur_max_bandwidth' value to 'op_mode_bw' which
matches the 'op_mode_nss', indicating more clearly what it _is_
rather than how it's _used_. It's not quite precise (NSS is)
since it's also HT chanwidth notification, but that seems OK.

This also fixes checks in two ways:
- Regulatory checks in nl80211_validate_ap_phy_operation() are
now done also on updates, disallowing enabling HE/EHT/UHR on
channels that don't allow that after start. This checks only
operation now, but clients can't use it without operation.

For now, keep the NULL chandef pointer and all that, but
clean up the initial handling of NSS/BW capabilities and
then apply the VHT operation mode on top of that. This

The arm-linux-gnueabi-gcc compiler, align the field followed by union
members, causing size of struct ieee80211_rx_status over skb->cb
(48 bytes). By investigation, the union member starts at offset 32,
and the offset of next field rate_idx is 36 instead of expected 33, and
the total size is (unexpected) 52.
When compiling rtw88 driver, it throws:

In the final version of 802.11be-2024, Transition Delay and Padding
Delay subfield are for both EMLSR and EMLMR. Depending if the mode is
EMLSR or EMLMR, the interpretation of the encoded value might change.
Define all the constants and helpers to interpret delay subfields both
in EMLSR and EMLMR mode.

In the finalized version of 802.11be-2024, the EMLMR delay values have
been merged in the EMLSR Padding/Transition Delay subfields and
therefore the subfield EMLMR Delay has been converted to a reserved field.
