6   A new packet is complete. Our goal here is to get back into receive
7   mode as fast as possible. On the Z85230 we could change to using
8   ESCC mode, but on the older chips we have no choice. We flip to the
9   new buffer immediately in DMA mode so that the DMA of the next
10   frame can occur while we are copying the previous buffer to an sk_buff
