set_feature patch will send as separate RFC patch along with
rx_checksum patch, as it needs further discussion related to HW

checksum.

Is this part relating to the crash you observed because of TCP csum
offload?

Yes, you are correct. Sergey, suggested use R-Car RX-HW checksum with RCSC/RCPT and
But the TOE gives either 0x0 or 0xffff as csum output and feeding this value to skb->csum
lead to kernel crash.

I'm trying to understand the situation before and after this series.
What makes the crash possible to trigger?
