[PATCH 0/4] wifi: rtw89: update address CAM size and PPDU parser to support WiFi 7 chips

[Ping-Ke Shih]

Patch 1/3 is to fill various entry size of address CAM accordingly, because
hardware designer shrinks size for new chips.

Patch 2/4 ~ 3/4 aim to adjust parser of RX PPDU status, the logic is almost
the same as existing, but size and fields are changed a little. The PPDU
packet looks like

 +---------------------------+
 |           RX WD           |  (RX WD is fixed length basically)
 | type = PDDU satus         |
 |                           |
 +---------------------------+
 | PPDU status - MAC part    |
 | * basic info (8 bytes)    |  (basic info indicates if following fields
 |   - usr_num               |   are existing)
 |   - with_rx_info          |
 |   - plcp_len              |
 | * usrs[usr_num]           |
 | * rx info(128 bytes opt.) |
 | * plcp[plcp_len]          |
 +---------------------------+
 |  PPDU status - PHY part   |
 | * basic info (8 bytes)    |
 |   - total length          |
 | * IEs[]                   |  (iterate all IEs within total length)

[PATCH 1/4] wifi: rtw89: set entry size of address CAM to H2C field by chip

[Ping-Ke Shih]

The new chips change hardware design to shrink entry size of address
CAM from 0x40 to 0x20, so make this change accordingly.

[PATCH 3/4] wifi: rwt89: consider RX info for WiFi 7 chips

[Ping-Ke Shih]

For WiFi 7 chips, some fields and predefined length are changed, so
add them accordingly.

The mac_id field is used to identify peer that send a packet, and we can
use it to know RSSI and traffic from the peer. For WiFi 7 chips,
RXWD.mac_id of PPDU status packet is not set by hardware. Instead, we
should fill it by rxinfo_user[].mac_id of PPDU status content.

Also, filter out invalid reports to prevent warning messages keep showing.

[PATCH 4/4] wifi: rtw89: extend PHY status parser to support WiFi 7 chips

[Ping-Ke Shih]

PHY status IEs is used to have more information about received packets,
such as RSSI and EVM. For each PHY IE type, it has different predefined
PHY IE length, and the length are changed, so add them for WiFi 7 chips
accordingly.
