The ENV_MNTR(environment monitor) is the dynamic mechanism which based on
the HW of CCX(Cisco Compatible Extensions) which provide the channel
loading and noisy level indicator to debug or support the 802.11k. The
PHYSTS provide the detail PHY information per packet we received for
debugging. The DIG(dynamic initial gain) is the dynamic mechanism to
adjust the packet detect power level by received signal strength to avoid
false detection of the WiFi packet.
The address of registers used for ENV_MNTR, PHYSTS and DIG of WiFi 7 IC
are different with WiFi 6 series, so we modify the method to access the
register address in order to compatible with all WiFi 7 and 6 ICs.

cr_base is base address of PHY control register. The base of WiFi 6 and 7
chips are 0x1_0000 and 0x2_0000 respectively, so define them accordingly.
For example, if PHY address is 0x1330, absolute address is 0x1_1330 for
WiFi 6 chips, and 0x2_1330 for WiFi 7 chips.
Meanwhile, there are two copies of PHY hardware named PHY0 and PHY1. The
offset between them is 0x2_0000, so the base address of PHY0 and PHY1 are
0x2_0000 and 0x4_0000 respectively.

To diagnose abnormal behavior, we need to dump certain internal memory.
For example, dump security CAM when debugging encryption/decryption
problems, or dump BA CAM when debugging abnormal BlockAck.
Since the indirect address and internal memory base address are different
between WiFi 6 and 7 chips, add fields to reuse codes.
Also, only WiFi 6 chips initialize DMAC and CMAC tables via this indirect
interface, so no need to change the constant register address, and
new firmware will help to initialize these tables.

There are two copies of MAC hardware called band0 and band1. Basically,

with a 'band' (or 'mac_idx') argument.
The offset of base address of WiFi 6 and 7 are 0x2000 and 0x4000

mac_gen_def to possibly reuse functions.

We prepare to deal with multiple channels via new entity modes.
* MCC_PREPARE: Transitional mode before MCC
* MCC: Multi-Channel Concurrent mode
And, enum of sub-entity is extended for second channel context.
We add the entry flow of multi-channel handling and the core stuffs
for extended index of sub-entity. And, we now deal with the filling
of entity channels' info in entity recalc where we know the number
of active chanctx. However, the other detail coding of MCC start/stop
will be implemented in the following.
Besides, chanctx listener struct is pre-added in chip info. Each
component can add callback type in chanctx listener and configure
its callback function to react according to chanctx states. We know
at least RFK (RF calibration) and BTC (BT coexistence) will require
such callbacks.

Callers call renew function when wanting to generate a new P2P NoA

* start MCC - GO part

append period NoA after calculation
* download beacon for GO

adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device. (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband

Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a

Wangxun NICs support the connection with SFP to RJ45 module. In this case,
PCS need to be configured in SGMII mode.
According to chapter 6.11.1 "SGMII Auto-Negitiation" of DesignWare Cores
Ethernet PCS (version 3.20a) and custom design manual, do the following
configuration when the interface mode is SGMII.
1. program VR_MII_AN_CTRL bit(3) [TX_CONFIG] = 1b (PHY side SGMII)
2. program VR_MII_AN_CTRL bit(8) [MII_CTRL] = 1b (8-bit MII)
3. program VR_MII_DIG_CTRL1 bit(0) [PHY_MODE_CTRL] = 1b
Also CL37 AN in backplane configurations need to be enabled because of the
special hardware design. Another thing to note is that PMA needs to be
reconfigured before each CL37 AN configuration for SGMII, otherwise AN will
fail, although we don't know why.
On this device, CL37_ANSGM_STS (bit[4:1] of VR_MII_AN_INTR_STS) indicates
the status received from remote link during the auto-negotiation, and
self-clear after the auto-negotiation is complete.
Meanwhile, CL37_ANCMPLT_INTR will be set to 1, to indicate CL37 AN is

Not calling hci_(dis)connect_cfm before deleting conn referred to by a
socket generally results to use-after-free.
When cleaning up SCO connections when the parent ACL is deleted too
early, use hci_conn_failed to do the connection cleanup properly.
We also need to clean up ISO connections in a similar situation when
connecting has started but LE Create CIS is not yet sent, so do it too
here.

There a few instances still using HCI_MAX_AD_LENGTH instead of using
max_adv_len which takes care of detecting what is the actual maximum
length depending on if the controller supports EA or not.

This commit implements defer setup support for the Broadcast Sink
scenario: By setting defer setup on a broadcast socket before calling
listen, the user is able to trigger the PA sync and BIG sync procedures
separately.
This is useful if the user first wants to synchronize to the periodic
advertising transmitted by a Broadcast Source, and trigger the BIG sync
procedure later on.
If defer setup is set, once a PA sync established event arrives, a new
hcon is created and notified to the ISO layer. A child socket associated
with the PA sync connection will be added to the accept queue of the
listening socket.
Once the accept call returns the fd for the PA sync child socket, the
user should call read on that fd. This will trigger the BIG create sync
procedure, and the PA sync socket will become a listening socket itself.
When the BIG sync established event is notified to the ISO layer, the
bis connections will be added to the accept queue of the PA sync parent.
The user should call accept on the PA sync socket to get the final bis
connections.

and make the code clearer and easier to update for new
