Subject: espintcp will crash kernel randomly

Hi Devs,

espintcp crash kernel random.

The last level of callstack are something like:

invalid opcode: 0000 SMP NOPTI
IRQ
tcp_gso_segment
...

if I use ethertool to disable gso tso gro, it will never crash again, why?

ethtool -K ens11 gso off gro off tso off

Tks,
Cong
