inb/outb and others are architecture (x86?) specific. The CI caught this issue, see build failures on ARM64. https://lab.dpdk.org/results/dashboard/results/results-uploads/test_runs/82432e287bc94831b7a65d7cd6f05783/log_upload_file/2021/2/dpdk_b49c677a0d24_15433_2021-02-01_00-15-59_NA.zip I can see the same issue with ppc64le. -- David Marchand
