[dpdk-dev] [PATCH] bus/ifpga: add a shared data structure to struct rte_afu_device

[Andy Pei <andy.pei@intel.com>]

Add a data structure rte_afu_shared to data structure rte_afu_device.
Struct rte_afu_shared contains a rte_spinlock_t and a void pointer.
This struct rte_afu_shared will be used in net/vbng.
