I'd say this is a bug in tcpdump(1), not a problem in the manual page. tcpdump(1) doesn't need an interface to process -d option. -- Totus tuus, Glebius.

ng_bpf(4) teaches to use tcpdump(1) to generate raw BPF instructions. However, the exact command line does not include '-p' option. This may activate promiscous mode on first ethernet interface, if any. This is not needed and should not happen. How-To-Repeat: Use example from bg_bpf(4) manual page and see pair of 'promiscuous mode enabled/promiscuous mode disabled' messages in the kernel log.
