Namely the --no-huge flag and --iova-mode=pa can't be used together and EAL init fails warning about a lack of access to physical addresses. This patchset tries to cleanup the --no-huge usage so that it doesn't hide the real state of tests when RTE_IOVA_PA is used (i.e. on platforms without IOMMU). I'm proposing to skip the no-huge test for RTE_IOVA_PA environments as it is not supported by design as well as removing no-huge usage on Linux as it seems that it is used (along with --no-shconf) to increase the compatibility with FreeBSD. Please let me know if I'm missing a bigger picture with the --no-huge and --no-shconf usage on non-FreeBSD platforms. I'm not adding stable@dpdk.org on purpose as this does not affect any current platform I'm aware of (at least in a production scenario). --- V2: - Fix checkpatch errors - Add affected platform in the cover letter.
