Ring Buffer Memory

When trying to increase the libpcap ring buffer capacity in argus.conf, it
does not appear to change anything on an Ubuntu system running argus.

We tried doing the same 2GB size with tcpdump using the -B option and
watched the memory usage climb dramatically as it should.

However, when trying to set using ARGUS_ENV="PCAP_MEMORY=2000000" there is
no increase in memory usage by argus at all.
