When parsing a devargs, try to parse using the global device syntax first. Fallback on legacy syntax on error. Example of new global device syntax: -a bus=pci,addr=82:00.0/class=eth/driver=mlx5,dv_flow_en=1 Signed-off-by: Xueming Li <redacted> --- lib/librte_eal/common/eal_common_devargs.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-)
