Ferruh,

Thanks for your contribution. Although I compiled Hiroyuki's patch with 
DPDK 17.11 release (tagged as v17.11) and there is no error, but error 
is occured after replacing DPDK latest.

...spp/src/vf/spp_vf.c:931:28: error: ‘RTE_LOG_LEVEL’ undeclared (first 
use in this function)
    rte_log_set_global_level(RTE_LOG_LEVEL);

...spp/src/vf/spp_vf.c:931:28: note: each undeclared identifier is 
reported only once for each function it appears in
/home/dpdk1711/dpdk-home/dpdk/mk/internal/rte.compile-pre.mk:114: ...

It is different from your error, but caused by rte_log. I think it is 
possibly because of a change of rte_log after 17.11 release. In any 
case, I think your change should be merged.

Thanks,
