Tested series on top of v7.3 + commit 7ed5dce55fa8 ("wifi: brcmfmac: map msgbuf RX packet IDs bidirectional") in wireless/main with resolving the conflict by dropping the conflicting hunk of this series. Tested on Mac mini (M1, BCM4378) and Macbook Pro 14-inch (M1 Max, BCM4387) without regressions (except for the resolved RX msgbuf mapping). Tested-by: Janne Grunau thanks, Janne
