Documentation patch is missing. Please add in 1/3. > +#define DLB2_DEFAULT_LDB_PORT_ALLOCATION_ARG "default_port_allocation" Please squash https://patches.dpdk.org/project/dpdk/patch/20220927001835.1394994-1-abdullah.sevin...@intel.com/ patch 1/3 here. Rest looks good. We should merge the next version.
