I cannot reproduce in my local fc28 system with the attached steps.
The netlink_dumper.c file, could you confirm whether the following
header files are missing form you rhel-7.2 host?
#include <linux/rtnetlink.h>
#include <linux/tc_act/tc_bpf.h>
I suspect you probably miss linux/tc_act/tc_bpf.h. But could you confirm
it? If this is the case, I can fix the problem by adding tc_bpf.h into
tools/include/uapi directory.
Thanks,
Yonghong
