net: dsa: sja1105: fix port mirroring for P/Q/R/S
The dynamic configuration interface for the General Params and the L2
Lookup Params tables was copy-pasted between E/T devices and P/Q/R/S
devices. Nonetheless, these interfaces are bitwise different.
The driver is using dynamic reconfiguration of the General Parameters
table for the port mirroring feature, which was therefore broken on
P/Q/R/S.
Note that this patch can't be backported easily very far to stable trees
(since it conflicts with some other development done since the
introduction of the driver). So the Fixes: tag is purely informational.

This is because the spi/spi2.1 switch doesn't support tagging anymore in
the SJA1105_VLAN_FILTERING_FULL state, so it doesn't need to have any
retagging rules defined. Great, so it can use more frame memory
(retagging consumes extra memory).
But the built-in low-level static config checker from the sja1105 driver
says "not so fast, you've increased the frame memory to non-retagging
values, but you still kept the retagging rules in the static config".
So we need to rebuild the VLAN table immediately before re-uploading the
static config, operation which will take care, based on the new VLAN
state, of removing the retagging rules.

wlcore: fix runtime pm imbalance in wlcore_irq_locked
When wlcore_fw_status() returns an error code, a pairing
runtime PM usage counter decrement is needed to keep the
counter balanced. It's the same for all error paths after
wlcore_fw_status().

rtw88: 8822c: remove CCK TX setting when switch channel
The CCK TX setting when switch channel will fix the CCK to
path A only, so if the antenna is configured to path B
(e.g. iw phy set antenna 0x2 0x3 "TX B/RX AB"), then the CCK
packets can never be delivered to the air if only path B is
connected with an antenna (it can possibly be transmitted
through path A, but as path B is configured, the expected
behavior is incorrect).
This can also solve the racing issue of CCK TX setting between
driver and firmware. The CCK TX setting in driver should be
removed. Otherwise, the CCK TX setting would be wrong when the
racing occurs.

rtw88: fix EAPOL 4-way failure by finish IQK earlier
Connecting to an AP with WPA2 security may fail. The IQK
and the EAPOL 4-way handshake may overlap because the
driver does IQK right after assoc success.
For 802.11n devices, the IQK is done in the driver and it
could require more than 100ms to complete. During IQK, any
TX/RX events are paused. So if the EAPOL 4-way handshake
started before IQK finished, then the 1/4 and 2/4 part of
the handshake could be dropped. The AP will then issue
deauth with reason IEEE8021X_FAILED (23).
To resolve this, move IQK routine into managed TX prepare
(ieee80211_ops::mgd_prepare_tx()). The callback is called
before the managed frames (auth/assoc) are sent. This will
make sure that the IQK is completed before the handshake
starts. But don't do IQK during scanning because doing it
on each channel will take too long.
For 802.11ac devices, the IQK is done in firmware and it
takes less time to complete. Therefore we don't see a
failure during the EAPOL 4-way handshake. But it is still
worth moving the IQK into ieee80211_ops::mgd_prepare_tx().

b43_legacy: Fix connection problem with WPA3
Since the driver was first introduced into the kernel, it has only
handled the ciphers associated with WEP, WPA, and WPA2. It fails with
WPA3 even though mac80211 can handle those additional ciphers in software,
b43legacy did not report that it could handle them. By setting MFP_CAPABLE using
ieee80211_set_hw(), the problem is fixed.
With this change, b43legacy will handle the ciphers it knows in hardware,
and let mac80211 handle the others in software. It is not necessary to
use the module parameter NOHWCRYPT to turn hardware encryption off.
Although this change essentially eliminates that module parameter,
I am choosing to keep it for cases where the hardware is broken,
and software encryption is required for all ciphers.

For rtw88 driver, the SDIO is going to be supported, so there is
no need to remove the SDIO related power sequence settings. And
while the power sequence parser will pass in the mask of the HCI,
the SDIO part will not be used to set registers accordingly.
Moreover, the power sequence table is released as a whole package,
so the next time if we are going to update, the SDIO settings will
be overwritten. So, revert this now.
I am leaving Quantenna, so I will no longer have access to firmware and
hardware. Meanwhile I plan to participate in reviewing qtnfmac patches
for a while until my firmware knowledge becomes completely obsolete.
