Issue

The packets received appear to be larger than the configured MTU in a packet capture. How can a packet trace show the packets received:

  • When the packets are larger than the MTU size?
  • When the packets are larger than a Jumbo frame (~9000 bytes)?

If packets larger than MTU are transmitted, see KB on the TSO/LSO: Transmitted packets appear to be larger than the configured MTU in a packet capture
