If an IP filter is applied in a packet capture (example below), Netronome Ethernet traffic is captured, although it is not IP traffic.

# capture reset
# segment all
# capture select 1 2 3
# capture filter ip 192.168.1.1
# capture start

Example of Packet Capture :
No.     Time     Source                Destination           SrcPort DstPort Protocol Info
      1 0.000    Netronom_00:00:01     Netronom_00:00:01                     0xcccf   Ethernet II
      2 12.491   Netronom_00:00:01     Netronom_00:00:01                     0xcccf   Ethernet II
      3 12.627   Netronom_00:00:01     Netronom_00:00:01                     0xcccf   Ethernet II
      4 15.754   192.168.1.1           10.10.10.10           57142   443     TCP      57142 > https [SYN]

The inclusion of the Netronome Ethernet traffic is working as designed. If there is a need to exclude this, a Feature Request should be submitted.
