In order to support multiple channels, we prepare this patchset to have initial skeleton of channel context, and only SCC (single channel concurrence) is supported for now. The channel context needs some features, like hardware scan, but not all chips can support these features, so this implement can still support chips without channel context. The chip_info defines a support_chanctx_num field to discriminate a chip can support channel context or not, and we use this as clue to hook channel context ops of mac80211. To determine if it can use channel context, load firmware header and parse firmware when probing before ieee80211_register_hw(). If chip defines it support channel context but firmware doesn't support hw_scan, it falls back to not use channel context. That means end users don't need additional update to use this driver after this patchset. When we concentrate stuffs of channel, some patches with a lot of changes are used to adjust code for new struct. But, not really change logic. v3: - to have good user experience after applying this patchset. Load firmware header and parse firmware features to determine if we can use channel context. If old firmware is adopted, it still can run well as original. v2: - patch 11/13: add link_id argument because ieee80211 ops prototype are changed. - patch 13/13: change to use module parameter rtw89_use_chanctx to prevent breaking users' setup by default, and users can try to use channel context after they upgrade firmware.
