[dpdk-dev] [PATCH] examples/l3fwd: force CRC stripping for i40evf

I should probably refer to the thread, where the concern was raised:
http://dpdk.org/ml/archives/dev/2016-July/044555.html

So, the issue is that i40evf *only support* CRC stripping for some
setups (i40e Linux driver for PF, i40evf DPDK driver VF).

The l3fwd application disables CRC stripping for all ports, which leads
to i40evf_dev_configure() failure -- which from my POV is correct.
Mis-configuring a port shouldn't be allowed.

I'm open to suggestions here. What would be a better way to solve this?
Maybe just adding a command-line option to the l3fwd application is a
better way around?
