PPE service code is a special code (0-255) that is defined by PPE for

For packet being sent out by ARM cores on Ethernet ports, The service
code 1 is used as the default service code. This service code is used
to bypass most of packet processing stages of the PPE before the packet
transmitted out PPE port, since the software network stack has already
processed the packet.
