[Description]:

Fixed one bug in PciBus. PciBus doesn't clear the bridges bus number for all the root bridges before scanning any of them.
[Description]:
 The static IP configuration no long works in the EDK 1.04 network package. The cause is that changing the type of EFI_IP4_IPCONFIG_DATA.RouteTable from a variable length array to a pointer is not clean. If the whole structure is read from variable, the pointer is invalid.
[Solution]
Fix the pointer before using it
[Impaction]:
 Ip4ConfigDxe module.
[Reference Info]:
 EDK tracker 1134 - Static IP configuration no long works.
