Neil, thank you for your reply.

I used the DPDK 8.1.0 setup.sh script to clean the system (unbind NICs,
rmmod igb_uio and uio, remove hugepage mappings), and then re-built for
x86_64-native-linuxapp-gcc, setup hugepages, insmod the modules, bound the
NICs, but have the same result when trying to run testpmd:
EAL: Error - exiting with code: 1
  Cause: No probed ethernet device


I then cleaned up again, downloaded DPDK 1.7.1 and ran the setup.sh script
to build for x86_64-native-linuxapp-gcc.  With 1.7.1, testpmd runs
successfully, and I am able to run my l3fwd command as well. I also built
for x86_64-ivshmem-linuxapp-gcc, and testpmd ran successfully (other than
the warning about no IVSHMEM configuration).

Thoughts?
