[dpdk-dev] [PATCH 1/4] librte_table: modify LPM table parameter structure

[Jasvinder Singh]

This patch relates to ABI change proposed for librte_table
(lpm table). A new parameter to hold the table name has
been added to the LPM table parameter structures
rte_table_lpm_params and rte_table_lpm_ipv6_params.
