Hi,=C2=A0

Is this test= ed on VFs? I saw crash on both PF as well as VF, on 20.11.1, but did not se= e PF crash on 20.11.3,=C2=A0
I'm seeing a crash on the second= ary process when it receives=C2=A0packet on the VF, but PF doesn't cras= h now on 20.11.3

So I suspect this is the patch wh= ich is fixing the=C2=A0issue on ICE secondary process crash on PF.

Thanks & Regards,
Navin Srinivas
