From: Pagadala Yesu Anjaneyulu Date: Wed, 30 Apr 2025 12:23:20 +0000 (+0300) Subject: wifi: iwlwifi: fw: support PPAG command version 7 X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=ad883b79b2b60006c92213d45546211267408c15;p=linux.git wifi: iwlwifi: fw: support PPAG command version 7 PPAG command version 7 will send exact data read from BIOS to firmware without filtering/altering BIOS data. This enables the driver to become purely a pipe for this feature.
