Thanks for the explanation, that clears up the SWDMA side.

I had read the RxDMA2 side as a separate case, and it looks like I have
that wrong too.  input_buf is max(max_input_len, SZ_4K) at
pci-quicki2c.c:607 while THC_RXDMA2 is sized ALIGN(max_input_len,
SZ_4K), and LNL leaves qcdev->ddata NULL so the max frame size feature
is never enabled.  I had assumed that gap was reachable, but you would
know whether it can be.

Either way, please drop the patch.  Thanks for taking a look at it.
