I just test compiled these patches and we have four new questions: Realtek 8822BU USB wireless network adapter (RTW88_8822BU) [N/m/?] (NEW) m Realtek 8822CU USB wireless network adapter (RTW88_8822CU) [N/m/?] (NEW) m Realtek 8723DU USB wireless network adapter (RTW88_8723DU) [N/m/?] (NEW) m Realtek 8821CU USB wireless network adapter (RTW88_8821CU) [N/m/?] (NEW) To me this looks too fine grained. Does it really make sense, for example, to enable RTW88_8822BU but not RTW88_8822CU? Would just having RTW88_USB containing all USB devices be more sensible? And the same for PCI, and if we have in the future, SDIO devices. But like discussed earlier, to keep things simple let's handle that separately from this patchset. -- https://patchwork.kernel.org/project/linux-wireless/list/ https://wireless.wiki.kernel.org/en/developers/documentation/submittingpatches
