Scan policies describe the way a bus should scan the system to search for possible devices. Three flags are introduced: RTE_BUS_SCAN_UNDEFINED: Configuration is irrelevant for this bus RTE_BUS_SCAN_WHITELIST: Scanning should be limited to declared devices RTE_BUS_SCAN_BLACKLIST: Scanning should exclude only declared devices Signed-off-by: Gaetan Rivet <redacted> --- lib/librte_eal/common/include/rte_bus.h | 17 +++++++++++++++++ 1 file changed, 17 insertions(+)
