Wi-Fi 7 Support on Banana Pi R4

Scope

Goal is to bringup Wi-Fi 7 on Banana Pi R4

Prerequisites

• • BSP migration - Mediatek MP release(Based on 2024q4 kirkstone) with 5.4 kernel
• Hostap2.11 migration - in sync with comcast revision

Features

• SLO with EHT rates for 2.4GHz/5GHz/6GHz
• 320 MHz on 6GHz with SLO
• MLO 
• 4KQAM - Depends on Vendor (Additional MCS rates)

Vendor checklist

• MLO configuration - is that through standard NL80211 or vendor based NL80211 (NL80211_VENDOR_*) or uci.

Modes

• 2.4Ghz/5Ghz (WPA3-Transition)
• 6Ghz - WPA3 personal

Testing

• Pixel 8
• S24 Ultra
• Intel BE clients - Available in CIEC chennai
• Candella Wi-Fi 7

Comcast kernel version

• 5.15

Wi-Fi Card

• BE14 card

Features dependent on WiFi-7 enablement:

• EasyMesh R6 migration

Code changes waiting to merge

• MLO code changes pending - will be available in 2 weeks

MLO update

• Supported Platform	Is that through generic implementation/Vendors interface
  #1	Using vendor interface
  #2	Using commands to driver

Wi-Fi 7 DMLs

• Using hardcoded configuration
• DML - Set/Get available soon .

Integration steps

• BSP migration
  • Manifest change
    • Update meta-filogic(4d1a2a549791f1d57c83d8be89927aed647b62ea) and meta-cmf-filogic(39973f0b37b6afef2be10640bedd9efb359530df) revision in below manifests 
      • https://code.rdkcentral.com/r/plugins/gitiles/manifests/+/refs/heads/kirkstone/rdkb-bpi-nosrc.xml
      • https://code.rdkcentral.com/r/plugins/gitiles/manifests/+/refs/heads/kirkstone/rdkb-bpi-extsrc.xml

  • Things to consider 

    • Port all configurations introduced in meta-cmf-broadband and meta-cmf-bananapi
• Hostap 2.11 upstep
  • get meta-rdk-broadband changes from beta release & enable 2.11 distro in distro.conf
• Wi-Fi 7 Testing 
  • Enable 80211BE_CONFIG
  • NEW_PLATFORM_PORT
• Unit testing 

Mediatek MP release

• MPmtk
