Add PCAP_IF_NO_INJECT and PCAP_IF_NO_CAPTURE to the list of known device flags. In show_devices_and_exit() do not print a shorthand number for and in find_interface_by_number() do not count no-capture devices. Update description on the "-D" flag in the man page. Before: 1.enp8s0 [Up, Running, Connected] 2.enp4s0 [Up, Running, Connected] 3.ens5 [Up, Running, Connected] 4.any (Pseudo-device that captures on all interfaces) [Up, Running] 5.lo [Up, Running, Loopback] 6.dag0 (alias for dag0:0) [none] 7.dag0:0 (Rx stream 0) [none] 8.dag0:1 (Tx stream 1) [none] 9.dag16 (alias for dag16:0) [none] 10.dag16:0 (Rx stream 0) [none] 11.dag16:1 (Tx stream 1) [none] 12.dag17 (alias for dag17:0) [none] 13.dag17:0 (Rx stream 0) [none] 14.dag17:1 (Tx stream 1) [none] 15.bluetooth-monitor (Bluetooth Linux Monitor) [Wireless] 16.nflog (Linux netfilter log (NFLOG) interface) [none] 17.nfqueue (Linux netfilter queue (NFQUEUE) interface) [none] After: 1.enp8s0 [Up, Running, Connected] 2.enp4s0 [Up, Running, Connected] 3.ens5 [Up, Running, Connected] 4.any (Pseudo-device that captures on all interfaces) [Up, Running, NoInject] 5.lo [Up, Running, Loopback] 6.dag0 (alias for dag0:0) [NoInject] 7.dag0:0 (Rx stream 0) [NoInject] dag0:1 (Tx stream 1) [NoCapture] 8.dag16 (alias for dag16:0) [NoInject] 9.dag16:0 (Rx stream 0) [NoInject] dag16:1 (Tx stream 1) [NoCapture] 10.dag17 (alias for dag17:0) [NoInject] 11.dag17:0 (Rx stream 0) [NoInject] dag17:1 (Tx stream 1) [NoCapture] 12.bluetooth-monitor (Bluetooth Linux Monitor) [Wireless, NoInject] 13.nflog (Linux netfilter log (NFLOG) interface) [NoInject] 14.nfqueue (Linux netfilter queue (NFQUEUE) interface) [NoInject]

This is one of the possible uses of the device flags in the-tcpdump-group/libpcap#1388, it may require more work.
