** Description changed:

+ SRU Justification:
+ 
+ [Impact]
+ 
+ Intel has only core102 PV firmware for AX211/BE211/BE213 on Intel
+ Wildcat Lake. While that's only supported by backport-iwlwifi-
+ dkms/release right now, we need to use it in linux-oem-6.17.
+ 
+ [Fix]
+ 
+ 1. for firmware, need to backport upstream commit b21b48725314
+ ("iwlwifi: add Bz/Wh FW for core102-56 release") to linux-
+ firmware/noble;
+ 
+ 2. for backport-iwlwifi, this depends on backport-iwlwifi fixes in bug
+ 2146804
+ 
+ [Test Plan]
+ 
+ Check wifi link availability with `ip` or `iw`.
+ 
+ [Where problems could occur]
+ 
+ backport-iwlwifi is not recommended whenever the in-tree module is
+ available and  supports the equipped hardware.
+ 
+ With the latest mainline v7.0-rcX kernel, the supported iwlwifi CoreAPI
+ is c101, and expecting to have c102 until v7.1 is released. It follows,
+ to retire the use of backport-iwlwifi-dkms in linux-oem-6.17, the linux-
+ hwe-7.0 is not sufficient and an even later HWE kernel from Ubuntu 26.10
+ should be used. We're still seeking the possibilities to retire
+ backport-iwlwifi as soon as possible.
+ 
+ [Other Info]
+ 
+ Nominate for kernel linux-oem-6.17 only, because linux/resolute is
+ already compiled with backport-iwlwifi core103.
+ 
+ Nominate for linux-firmware/noble only, because the required firmware
+ blobs are already in linux-firmware/resolute.
+ 
+ ========== original bug report ==========
+ 
  The PV firmware iwlwifi-bz-b0-wh-b0 for Intel BE211(WhP2)/BE213(SpP2) is
  going to be released with firmware Core API 102, and that's only
  available since mainline kernel v7.2 (currently core101 for v7.1-rc5).
  By pulling backport-iwlwifi-dkms/resolute version >= 1:0~103 to linux-
  oem-6.17 dkms-versions, we may use prebuilt linux-modules-iwlwifi to
  support aforementioned wireless hardware with linux-oem-6.17 in Noble.
  
  The proposed firmware are:
