When use "Intel PRO/1000 PT Quad Port Low Profile Server Adapter"
card on P5040DS and T1040RDB, 32-bit kernel does not identify this
card. This card has the four RJ-45 ports.
The bus range of every pci is "bus-range = <0 0xff>" in dts file.
So the first bus number of every pci should start from 0, and it
does not start from next_busno. The next_busno is used to count
the bus sum of all pci devices. So the value of next_busno is
accumulated.
This patch fixes this issue, and "Intel PRO/1000 PT Quad Port Low
Profile Server Adapter" card can work rightly.
