> Subject: [PATCH v10 1/3] lib/lpm: integrate RCU QSBR
>
> Currently, the tbl8 group is freed even though the readers might be using the
> tbl8 group entries. The freed tbl8 group can be reallocated quickly. This
> results in incorrect lookup results.
>
> RCU QSBR process is integrated for safe tbl8 group reclaim.
> Refer to RCU documentation to understand various aspects of integrating
> RCU library into other libraries.
>
> To avoid ABI breakage, a struct __rte_lpm is created for lpm library internal
> use. This struct wraps rte_lpm that has been exposed and also includes
> members that don't need to be exposed such as RCU related config.
