[dpdk-dev] [PATCH v2 0/2] Increase number of next hops for LPM IPv4

This patchset extend next_hop field from 8-bits to 24-bits in LPM library for IPv4.

As next_hop field is increased now the maximum number of tbl8s is 2^24. 
A new rte_lpm_config structure is used so LPM library will allocate
exactly the amount of memory which is necessary to hold application’s rules.

Changed structures in LPM library:
rte_lpm_tbl24_entry and rte_lpm_tbl8_entry to one structure rte_lpm_tbl_entry.

Added versioning symbols to functions and updated
library and applications that have a dependency on LPM library.

Michal Kobylinski (2):
  lpm: extend ip4 next_hop and add config structure
  examples: update to use new lpm lib for ip4
