If anyone has any objections, please let me know. ------------------ From: Bitterblue Smith commit 83d38df6929118c3f996b9e3351c2d5014073d87 upstream. Bit 28 of double word 2 in the RX descriptor indicates if the packet is a normal 802.11 frame, or a message from the wifi firmware to the driver (Card 2 Host). Commit f5678bfe1cdc ("rtlwifi: rtl8821ae: Replace local bit manipulation macros") mistakenly made the driver look for this bit in double word 1, causing packet loss and Bluetooth coexistence problems.
