Add comment about why checking for 0xff is OK. There's two bits in the
ISR that are normally clear. RST is one, though in some overflow cases
it can be set. RDC is only set when a remote DMA is finished from the
memory mapped memory to the transmit rings, which we poll fore in the
code with ED_LOCK around the operation that would set it.
