Hi Jerin, Are you planning increase next_hop field for ARM? I extended next_hop field from 8 bits to 24 bits and created structure to configure LPM for x86. Please look at my patchset with proposal increase next_hop field and structure to configure. http://patchwork.dpdk.org/dev/patchwork/patch/10249/ http://patchwork.dpdk.org/dev/patchwork/patch/10250/ Best Regards, Michal
