This is a bit odd. MTU is Maximum Transmission Unit, so clearly is
about Tx. MRU does not really exist. Does TCP allow for asymmetric
MTU/MRU? Does MTU discovery work correctly for this?
In general, it seems like drivers implement min(MTU, MRU) and nothing
more. Do you have a real use case for this asymmetry?
