[Thomas Monjalon]

Can we have this patchset in 18.05-rc1?
Or is it candidate to rc2?

> but it is definitely more heavy-weight than ring/stack drivers.
> The driver will be used by the future Solarflare driver enhancements

> The target usecase is dequeue in blocks and enqueue separate objects
> back (which are collected in buckets to be dequeued). So, the memory
> pool with bucket driver is created by an application and provided to
> networking PMD receive queue. The choice of bucket driver is done using
> rte_eth_dev_pool_ops_supported(). A PMD that relies upon contiguous
> block allocation should report the bucket driver as the only supported
> and preferred one.
