After doing both of these I get some more detail: bill@Ubuntu15:~/linaro/review/example/l2fwd_simple$ ./l2fwd_simple_run.sh using PCAP_IN = ./udp64.pcap _ishm.c:859:_odp_ishm_reserve():No huge pages, fall back to normal pages. check: /proc/sys/vm/nr_hugepages.

My recollection is that the last time I successfully ran pcap stuff we prior to the integration of the _ishm code. > > -Matias >
