[dpdk-users] segfault with dpdk 16.07 in rte_mempool_populate_phys

[martin_curran-gray at keysight.com]

Hi Shreyansh

Found my problem, because of the way the dpdk is integrated into our sw as a prebuilt library, we don't get the automatic initialisation of objects the way I think the dpdk examples benefit from.
I'd forgotten this, we have explicit calls to things like

devinitfn_rte_i40e_driver();

so after I added an explicit call to

mp_hdlr_init_ops_mp_mc();

my function pointer deep down below  rte_mempool_create is now valid.

Seem to have a nice performance improvement of about 40% in the rate my app can handle at the front door compared to 2.2.0

Nice

Now I just need to find out why when I turn on vector mode, I never get any mbuffs returned to the pool :)

Thanks for your help

Martin
