Set the size of the receive descriptor ring. Valid values: 512, 1024, 2048 or 4096.

A larger ring size can absorb larger packet bursts without drops, but might reduce efficiency because the working set size is increased.

If the value is lower than is supported by the hardware, it is rounded up. Set EF_LOG to include more_config_warnings to log if this occurs.
