Keep free packets number to be at least this value. EF_MIN_FREE_PACKETS defines initialization behavior, and this value is about normal application runtime. In some combinations of hardware and software, Onload is not able allocate packets at any context, so it makes sense to keep some spare packets. Default value 0 is interpreted as EF_RXQ_SIZE /2.
