From fef63150940c2aaa50721dde33d48f00ab510591 Mon Sep 17 00:00:00 2001 From: Zong-Zhe Yang Date: Mon, 19 Aug 2024 17:17:24 +0800 Subject: [PATCH] wifi: rtw89: introduce chip support link number and driver MLO capability Configure supported link number by chip. And, introduce driver capability flag for MLO. Driver should depend on runtime FW features and chip info to determine whether to set the MLO capability flag or not. Once the MLO flag is set, driver will consider/register/initialize things for MLO usages. However, we just add the driver MLO capability flag ahead and don't really set it. Then, we can start to tweak driver architecture for MLO. Some code should depend on this flag. And after tweaking driver architecture is done, we will set it based on runtime conditions as mentioned above. Besides, MLD number supported by HW should be chip supported mac_id number / chip supported link number Without driver MLO capability flag, we allocate stations based on supported mac_id number. With driver MLO capability flag, we allocate stations based on supported MLD number.
