When this kind of stuff doesn't work it often will depend on the exact version
of card, chip, etc. if there are any errata.
So you might want to collect the specifics of the board with lspci -v,
ethtool, and pulling it out to check the chip and board revisions.
In addition check over the example apps and see how things work there compared
with your own code. Often the DPDK interfaces are kind of complex and small
pointer or mbuf manipulation mistakes can cause very odd results.
