Agreed. Please go a head and make the changes. You need to make same change in kernel side also. And please use c11 ring (see rte_ring) mechanism so that it won't impact other platforms like intel. We need this change just for arm and ppc. From: Honnappa Nagara

I agree with Gavin here. Store to fifo->write and fifo->read can get hoisted resulting in accessing invalid buffer array entries or over writing of the buffer array entries. IMO, we should solve this using c11 atomics. This will also help remove the use of 'volatile' from 'rte_kni_fifo' structur
