Hello Stephen,

Thanks for your kindly review.

sssnic_workq is quite different from rte_ring, it's used to maintain 
information of hardware work queue, like Rx work queue, Tx work queue 
etc. Unlike rte_ring the elements of sssnic_workq are organized in a 
blcok of contiguous DMA memory accessed by hardware work queue, in 
addition the sssnic_workq records CI(consumer index) and PI(producer 
index) that synchronize with hardware work queue, driver generally 
accesses element of sssnic_workq by PI or CI.  Therefore I don't think 
rte_ring is suitable for sssnic_workq.
