Thanks.  I found two problems so far.

One is that using -P and -s together doesn't work because we haven't
scanned the entire topology.

$ ./lspci-mw -PF tests/fujitsu-p8010.lspci -s 1d:00.0
00:1e.0/03.0/00.0 Network controller: 3Com Corporation 3com 3CRWE154G72 [Office Connect Wireless LAN Adapter] (rev 01)
$ ./lspci-mm -PF tests/fujitsu-p8010.lspci -s 1d:00.0
1d:00.0 Network controller: 3Com Corporation 3com 3CRWE154G72 [Office Connect Wireless LAN Adapter] (rev 01)

The other is that even when not using -s, the topology isn't fully represented:

$ ./lspci-mm -PF tests/fujitsu-p8010.lspci |grep 3com
00:1e.0/00.0 Network controller: 3Com Corporation 3com 3CRWE154G72 [Office Connect Wireless LAN Adapter] (rev 01)

I've attached a compressed form of the fujitsu-p8010.lspci dump for your
testing.
