Summary

A race condition was found in the Linux virtual ethernet (veth) driver that affected AF_XDP enabled devices by corrupting packets. The issue was fixed by ensuring that all packet processing operations were completed before signaling the NAPI poll as complete. This bug was important to fix because it slightly increased the latency of connection establishments and data transfers across the network.
