    "content": "Currently in DPDK, any checks for the presence or absense of specific\nCPU flags has to be enclosed in #ifdef blocks, since the flags are\nconditionally defined per architecture as enums. This set attempts to\nimprove this situation by allowing the flags to be queried as strings,\nwith a CPU architecture type also specified. One new public API is\nprovided for this. [Other APIs used by that are internal for now, but\nhave an rte_ prefix in case we want to expose them publically later]\n\nTo test out this new functionality the crc code in the net library is\nupdated to use this, demonstrating how the code can be simplified and\nthe use of #ifdef's reduced.\n\nBruce Richardson (4):\n  build: fix quoting on RTE_ARCH string value\n  config/arm: fix missing define for arm platforms\n  eal: allow checking CPU flags by name\n  net: replace ifdefs with runtime branches\n\n config/arm/meson.build                        |  2 +\n config/ppc_64/meson.build                     |  2 +-\n config/x86/meson.build                        |  4 +-\n lib/librte_eal/common/eal_common_cpuflags.c   | 41 +++++++++++++++++\n .../common/include/generic/rte_cpuflags.h     | 44 ++++++++++++++++++-\n lib/librte_eal/rte_eal_version.map            |  3 ++\n lib/librte_net/rte_net_crc.c                  | 38 ++++++++++------\n 7 files changed, 117 insertions(+), 17 deletions(-)"
