Question

When I set debug kernel console level to 8, I can see many log “kernel: Port x receive error code 10, packet dropped”, what does it mean?

Answer

The error debug code is normal behavior, it shows that when device receive Ethernet packets with incorrect length. It mostly happens when some network equipment doing wrong padding for minimize size Ethernet packet (64+4FCS bytes, should be 60+4FCS bytes).
