realtek: Increase zone size for Ethernet driver DMA
Set CONFIG_FORCE_MAX_ZONEORDER setting to 13 to allow larger
contiguous memory allocation for the DMA of the Ethernet
driver. Increase the number of entries in the RX ring
to 300 making use of the larger DMA region now possible for
receiveing packets.
