5f93676830 wifi: rtw88: enable TX reports for the management queue
This is needed for AP mode. Otherwise client sees the network, but
can't connect to it.

REG_FWHW_TXQ_CTRL+1 is set to WLAN_TXQ_RPT_EN (0x1F) in common mac
init function (__rtw8723x_mac_init), but the value was overwritten
from mac table later.

Tables with register values for phy parameters initialization are
copied from vendor driver usually. When table will be regenerated,
manual modifications to it may be lost. To avoid regressions in this
case new callback mac_postinit is introduced, that is called after
parameters from table are set.

Tested on rtl8723cs, that reuses rtw8703b driver.

b74947b4f6 wifi: cfg80211/mac80211: Add support to get radio index
Currently, per-radio attributes are set on per-phy basis, i.e., all the
radios present in a wiphy will take attributes values sent from user. But
each radio in a wiphy can get different values from userspace based on
its requirement.

To extend support to set per-radio attributes, add support to get radio
index from userspace. Add an NL attribute - NL80211_ATTR_WIPHY_RADIO_INDEX,
to get user specified radio index for which attributes should be changed.
Pass this to individual drivers, so that the drivers can use this radio
index to change per-radio attributes when necessary. Currently, per-radio
attributes identified are:
NL80211_ATTR_WIPHY_TX_POWER_LEVEL
NL80211_ATTR_WIPHY_ANTENNA_TX
NL80211_ATTR_WIPHY_ANTENNA_RX
NL80211_ATTR_WIPHY_RETRY_SHORT
NL80211_ATTR_WIPHY_RETRY_LONG
NL80211_ATTR_WIPHY_FRAG_THRESHOLD
NL80211_ATTR_WIPHY_RTS_THRESHOLD
NL80211_ATTR_WIPHY_COVERAGE_CLASS
NL80211_ATTR_TXQ_LIMIT
NL80211_ATTR_TXQ_MEMORY_LIMIT
NL80211_ATTR_TXQ_QUANTUM

By default, the radio index is set to -1. This means the attribute should
be treated as a global configuration. If the user has not specified any
index, then the radio index passed to individual drivers would be -1. This
would indicate that the attribute applies to all radios in that wiphy.

57d6be36cf wifi: rtw88: Rename the RTW_WCPU_11{AC,N} enums
The RTW_WCPU_11AC and RTW_WCPU_11N enums are used to identify two
types of microcontrollers used in Realtek chips, but these names are
misleading. The "11AC" type was also used in 11n devices (e.g.
RTL8733BU, not supported by rtw88), and the "11N" type was also used
in 11ac devices (RTL8821AU, RTL8812AU).

Rename RTW_WCPU_11AC to RTW_WCPU_3081 and RTW_WCPU_11N to RTW_WCPU_8051.
(8051 is well known. It's less clear what 3081 is, but the out of tree
drivers use this name.)

b8d49bb8d1 wifi: rtw88: Don't set SUPPORTS_AMSDU_IN_AMPDU for RTL8814AU
RTL8814AU doesn't work well with SUPPORTS_AMSDU_IN_AMPDU. The RX speed
is noticeably lower and the VHT RX statistics are strange. Typical
values with SUPPORTS_AMSDU_IN_AMPDU:

b19840afc0 wifi: rtw88: coex: Support chips without a scoreboard
All the chips currently supported have a "scoreboard": the chip keeps
track of certain things related to bluetooth, for example, whether
bluetooth is active. The information can be read from register 0xaa.

RTL8821AU doesn't have this. Implement bluetooth activity detection in
rtw_coex_monitor_bt_enable() based on the bluetooth TX/RX counters.

This is mostly important for RTL8811AU, the version of RTL8821AU without
bluetooth. Without this change, the driver thinks bluetooth is active
and the wifi speeds are low.

The TX page size is used, among other things, to construct the beacon,

the chip's reserved page. Each template needs to be aligned on a
multiple of the TX page size. Power saving can't work if the TX page

each RF path, so make it an array of size RTW_RF_PATH_MAX (4).

Until now all the chips using this had only one RF path, but RTL8812AU
has two, and RTL8814AU has four.

c7706b1173 wifi: rtw88: Enable data rate fallback for older chips
RTL8811AU fails to perform the 4-way handshake when the AP is too far
because it transmits the EAPOL frames at MCS9 and when that doesn't
work it retries 48 times with the same rate, to no avail.

Retrying 48 times with the same rate seems pointless. Set the
appropriate field in the TX descriptor to allow it to use lower rates
when retrying.

Set it for RTL8723D and RTL8703B because they interpret this field the
same way as RTL8811A.

The newer RTL8822C, RTL8822B, RTL8821C seem to interpret this field in
the TX descriptor differently, so leave it alone for those chips.

Tested with RTL8811AU and RTL8723DU.

902cb7b11f wifi: rtw88: assign mac_id for vif/sta and update to TX desc
A mac_id as an instance in firmware has to be assigned for each station
including AP and connected stations. Firmware will use the mac_id to
control TX rate and do statistics.

Assignment rule is to assign mac_id to each vif when adding vif.
For station mode, sta->mac_id will reuse vif->mac_id. For AP mode,
dynamically allocate an sta->mac_id to a station, and vif->mac_id is
used to send broadcast/multicast packets which are not belong to
a station. For example,

                  vif->mac_id      sta->mac_id
vif0 (STA mode)        0               0
vif1 (AP mode)         1               2...

By the way, remove unused RTW_BC_MC_MACID, which was planed to send
broadcast/multicast packets on fixed mac_id.

Tested-on RTL8822CE with STA + AP SCC mode.

The Realtek wifi 5 devices which support USB 3 are weird: when first
plugged in, they pretend to be USB 2. The driver needs to send some
commands to the device, which make it disappear and come back as a
USB 3 device.

Implement the required commands in rtw88.

When a USB 3 device is plugged into a USB 2 port, rtw88 will try to
switch it to USB 3 mode only once. The device will disappear and come
back still in USB 2 mode, of course.

Some people experience heavy interference in the 2.4 GHz band in
USB 3 mode, so add a module parameter switch_usb_mode with the
default value 1 to let people disable the switching.

d7dd13ea54 wifi: rtw88: usb: Further limit the TX aggregation
Currently the number of frames sent to the chip in a single USB Request
Block is limited only by the size of the TX buffer, which is 20 KiB.
Testing reveals that as many as 13 frames get aggregated. This is more
than what any of the chips would like to receive. RTL8822CU, RTL8822BU,
and RTL8821CU want at most 3 frames, and RTL8723DU wants only 1 frame
per URB.

RTL8723DU in particular reliably malfunctions during a speed test if it
receives more than 1 frame per URB. All traffic seems to stop. Pinging
the AP no longer works.

Fix this problem by limiting the number of frames sent to the chip in a
single URB according to what each chip likes.

Also configure RTL8822CU, RTL8822BU, and RTL8821CU to expect 3 frames
per URB.

RTL8703B may or may not be found in USB devices. Declare that it wants
only 1 frame per URB, just in case.

Tested with RTL8723DU and RTL8811CU.

ffa71c5477 wifi: rtw88: 8822c: extend reserved page number
Extend 8822c's reserved page number to accommodate additional required
pages. Reserved page is an area of memory in the FIFO dedicated for
special purposes. Previously only one interface is supported so 8 pages
should suffice, extend it so we can support 2 interfaces concurrently.

ccf73f6e69 wifi: rtw88: add port switch for AP mode
Switch port settings if AP mode does not start on port 0 because of
hardware limitation. For some ICs, beacons on ports other than zero
could misbehave and do not issue properly, to fix this we change AP
VIFs to port zero when multiple interfaces is active.

f0e741e4dd wifi: rtw88: add bitmap for dynamic port settings
In order to support multiple interfaces, multiple port settings will
be required. Current code always uses port 0 and should be changed.
Declare a bitmap with size equal to hardware port number to record
the current usage.

4a267bc5ea wifi: rtw88: use RTW_FLAG_POWERON flag to prevent to power on/off twice
Use power state to decide whether we can enter or leave IPS accurately,
and then prevent to power on/off twice.

The commit 6bf3a08340 ("wifi: rtw88: add flag check before enter or leave IPS")
would like to prevent this as well, but it still can't entirely handle all
cases. The exception is that WiFi gets connected and does suspend/resume,
it will power on twice and cause it failed to power on after resuming,
like:

  rtw_8723de 0000:03:00.0: failed to poll offset=0x6 mask=0x2 value=0x2
  rtw_8723de 0000:03:00.0: mac power on failed
  rtw_8723de 0000:03:00.0: failed to power on mac
  rtw_8723de 0000:03:00.0: leave idle state failed
  rtw_8723de 0000:03:00.0: failed to leave ips state
  rtw_8723de 0000:03:00.0: failed to leave idle state
  rtw_8723de 0000:03:00.0: failed to send h2c command

To fix this, introduce new flag RTW_FLAG_POWERON to reflect power state,
and call rtw_mac_pre_system_cfg() to configure registers properly between
power-off/-on.
