Hi.

When using lspci in tree mode, a PCI bridges are not displayed:

One can see, that
# lspci -n | egrep '1c.0|1c.2|1e.0'
00:1c.0 0604: 8086:2660 (rev 03)
00:1c.2 0604: 8086:2664 (rev 03)
00:1e.0 0604: 8086:2448 (rev d3)

# lspci -v -n | egrep '1c.0|1c.2|1e.0'
00:1c.0 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI
Express Port 1 (rev 03)
00:1c.2 PCI bridge: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) PCI
Express Port 3 (rev 03)
00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev d3)


I think showing PCI bridges would be usefull, and will actually simplify
tree rendering, by showing bridge always on the first position in the subtree.

Regards,
Witek
