I prefer to keep the similar output format to wireshark dumpcap

I.e:

$ dumpcap -D
1. enp2s0
2. any
3. lo (Loopback)
4. wlo1
5. bluetooth0
6. bluetooth-monitor
7. nflog
8. nfqueue
9. dbus-system
10. dbus-session

With testpmd running with three interfaces

# dpdk-dumpcap -D
0. net_null0
1. net_null1
2. net_null2
