Neil, your patch works.  I am now able to run testpmd, as well as l3fwd
with DPDK 1.8.0 and CONFIG_RTE_BUILD_COMBINE_LIBS=y.  Thank you much!

In my original post, I thought my choice of hex portmask -p 0x3 was causing
this issue -- now I know that was not the case.  But, I am still curious
about how the hex portmask is determined.  Since I only have two ports
bound to igb_uio, my hex postmask will always be 0x3?  What if I choose to
bind other ports to igb_uio?  Is there a Linux command I can run to
determine what mask to use with the -p option?

Happy New Year --
Lyn
