Device or driver does not support multiple page network buffers, so it
tries to allocate huge buffer (4 pages) for each packet.
I can not find eth_rx_fill() function in a recent kernel, so maybe
driver was rewritten after .22 release and now supports per-page split
of the packet, so it will happily live with jumbo frames.
