Olivier Matz cb8fac62be efd: fix build by removing dependency to libmath ... When we compile the dpdk with: CONFIG_RTE_LIBRTE_EFD=y CONFIG_RTE_LIBRTE_NFP_PMD=n CONFIG_RTE_LIBRTE_THUNDERX_NICVF_PMD=n CONFIG_RTE_LIBRTE_SCHED=n CONFIG_RTE_LIBRTE_METER=n The linker gives the following error: lib/librte_efd.a(rte_efd.o): In function `rte_efd_create': lib/librte_efd/rte_efd.c:560: undefined reference to `log2' collect2: error: ld returned 1 exit status This is because the '-lm' is missing in mk/rte.app.mk. An alternative, which is proposed by this patch, is to use the compiler builtin rte_bsf32() to process log2 instead of the libmath log2() that requires to include math.h and link with -lm.
