When packet buffer's payload buffer does not have enough contiguous
window left, the ring buffer roll over uses an incorrect size
causing the ring buffer pointer not resetting to the head.
When the payload enqueued is larger than 1/2 of the payload ring
buffer, this bug will cause the slice returned by
PacketBuffer::enqueue
to not match the requested size, andtrigger
debug_assert
in debug profile or size mismatch panic incopy_from_slice
when compiled in release profile.
