It also started happening sometime in the lifetime of 8-STABLE some months ago, with "netstat -i" showing usbus network interfaces despite no ethernet NIC being attached. It appears that "ifconfig" is smart enough to omit these in output, as was netstat in former times on RELENG_8 (and still is on RELENG_7), so why include them now? Just wondering...
I've been wondering as well, since all of a sudden tcpdump needs me to
specify the adaptor..
root at server:~# tcpdump
tcpdump: WARNING: usbus0: no IPv4 address assigned
tcpdump: unsupported data link type USB
root at server:~# tcpdump -i nfe0
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on nfe0, link-type EN10MB (Ethernet), capture size 96 bytes
