BRIDGE_ID2 - Bridge ID Register
The Bridge ID register identifies the PCI bridge for port 2 for which this set of per-port
functions are valid. S/W can query the bridge’s configuration registers to determine
which I/O devices are downstream of the bridge and thus can use this set of per-port
DMA Engine resources. Note that only one of those down stream devices can use
Stream Priority capability at a time (see In-Use bit).
BRIDGE_ID3 - Bridge ID Register
The Bridge ID register identifies the PCI bridge for port 3 for which this set of per-port
functions are valid. S/W can query the bridge’s configuration registers to determine
which I/O devices are downstream of the bridge and thus can use this set of per-port
DMA Engine resources. Note that only one of those down stream devices can use
Stream Priority capability at a time.
