> Subject: [RFC PATCH 0/3] RCU integration with LPM library
> 
> This patchset integrates RCU QSBR support with LPM library.
> 
> Document is added with suggested design of integrating RCU library with other
> libraries in DPDK.
> As an example, LPM library adds the integration. RCU is used to safely free tbl8
> groups that can be recycled. Table will not be reclaimed or reused until reader
> finished referencing it.
> 
> New API rte_lpm_rcu_qsbr_add is introduced for application to register a RCU
> variable that LPM library will use.
> 
> New API rte_ring_peek is introduced to help on management of reclaiming
> FIFO queue.
