Thu Aug 22 08:34:54 CEST 2019
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.
