Once we connect to AP with 802.11w enabled, IGTK rekey happen during GTK happen. We get IGTK IPN from mac80211 and set to firmware, and get latest IGTK IPN from AOAC report then update to mac80211 after resume. When rekey happen, also update new IGTK key info to mac80211.

After enabling packet offload, the TX will be stuck after resume from WoWLAN mode. And the 8852c gets error messages like rtw89_8852ce 0000:04:00.0: No busy txwd pages available rtw89_8852ce 0000:04:00.0: queue 0 txwd 100 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 101 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 102 is not idle rtw89_8852ce 0000:04:00.0: queue 0 txwd 103 is not idle If suspend/resume many times that firmware will download failed and disconnection. To fix these issues, We removed the rtw89_hci_disable_intr() and rtw89_hci_enable_intr() during rtw89_wow_swap_fw() to prevent add packet offload can't receive c2h back due to interrupt disable. Only 8852C and 8922A needs to disable interrupt before downloading fw. Furthermore, we avoid using low power HCI mode on WoWLAN mode, to prevent interrupt enabled, then get interrupt and calculate RXBD mismatched due to software RXBD index already reset but hardware RXBD index not yet.

Remove unnecessary includes from driver. The first step is to add necessary includes to driver's header files to make them can be included individually. Then, driver's C files include driver's header files first, and check if still missed header files of kernel. The results show that most C files only include driver's header files. Only core.c needs to include additional linux/firmware.h. Also sort includes in alphabetic order. Compile tested only. Signed-off-by:

The driver is already in a directory named rtl8xxxu, there's no need to duplicate that in the filename as well. Now file listing looks a lot more reasonable: 8188e.c 8192c.c 8192f.c 8723a.c core.c Makefile rtl8xxxu.h 8188f.c 8192e.c 8710b.c 8723b.c Kconfig regs.h No functional changes, compile tested only.

I noticed by random that rtl8xxxu includes linux/wireless.h even though it doesn't need it. While investigating a bit more I found even more unused include files: #include <linux/init.h> #include <linux/sched.h> #include <linux/ethtool.h> It looks like that the includes are just copied to every file without checking if the file really needs the include. So more includes could be removed but that would need more careful analysis per each file. No functional changes, compile tested only. Signed-off-by:

Create the new module rtl8192d-common and move some code into it from rtl8192de. Now the rtl8192de driver (PCI) and the new rtl8192du driver (USB) can share some of the code. This is mostly the code that required little effort to make it shareable. There are a few more functions which they could share, with more changes. Add phy_iq_calibrate member to struct rtl_hal_ops to allow moving the TX power tracking code from dm.c. The other changes in this patch are adjusting whitespace, renaming some functions, making some arrays const, and making checkpatch.pl less unhappy. rtl8192de is compile-tested only. rtl8192d-common is tested with the new rtl8192du driver.

Structs rx_desc_92d and rx_fwinfo_92d will not work for big endian systems. Delete rx_desc_92d because it's big and barely used, and instead use the get_rx_desc_rxmcs and get_rx_desc_rxht functions, which work on big endian systems too. Fix rx_fwinfo_92d by duplicating four of its members in the correct order. Tested only with RTL8192DU, which will use the same code. Tested only on a little endian system.

Some (all?) management frames are incorrectly reported to mac80211 as decrypted when actually the hardware did not decrypt them. This results in speeds 3-5 times lower than expected, 20-30 Mbps instead of 100 Mbps. Fix this by checking the encryption type field of the RX descriptor. rtw88 does the same thing. This fix was tested only with rtl8192du, which will use the same code. Cc: stable@vger.kernel.org Signed-off-by:

Different channels have different TX power settings. rtl8192de is using the TX power setting from the wrong channel in the 5 GHz band because _rtl92c_phy_get_rightchnlplace expects an array which includes all the channel numbers, but it's using an array which includes only the 5 GHz channel numbers. Use the array channel_all (defined in rtl8192de/phy.c) instead of the incorrect channel5g (defined in core.c). Tested only with rtl8192du, which will use the same TX power code.
