IP Truncated-ip problem

I ran into a weird network problem today:

1. A machine has a high Ping packet latency or a large number of packet losses.

2. The load is so low that nothing is done.

For the first time, grab the bag and take a look at the situation:

It is clear that the original packet should be 64 bytes, but the machine only received 43 of its own, missing 21 bytes!

God, what's wrong?

This is often caused by the driver or the underlying kernel module processing the packet, because a memory copy may be involved in the transfer of the packet.

It is recommended that the latter check the kernel module for resolution by upgrading the driver.
