Hi,I have add QEMU_IFLA_INFO_KIND nested type for sit.But I still can't open Google browser.
And there are still the following errors:

qemu: uncaught target signal 5 (Trace/breakpoint trap) - core dumped

Qemu get the signal(INT3).
What causes this signal???

I don't know how to debug. When I block the operation of int3 in QEMU,
it has the following error:

qemu: 0x4004bc7855: unhandled CPU exception 0x3 - aborting

Is it possible that the CPU of arm does not support certain instructions?But，I don't know.
Who can give me some advice?
Thank you！
