> Limiting the memcpy to be the sizeof(struct rndis_message) can truncate
> the message if there are Per-Packet-Info or Out-of-Band data.
> In my earlier patch (commit 45326342), the unnecessary kmap_atomic and
> kunmap_atomic surrounding this memcpy have been removed because the memory
> in the receive buffer is always mapped. This memcpy is not necessary
> either. To fix the bug, I removed the memcpy.
