Description
Reserved.
When the LAN Function Select field = 0b, LAN 0 is routed to PCI function 0 and
LAN 1 is routed to PCI function 1. If the LAN Function Select field = 1b, LAN 0
is routed to PCI function 1 and LAN 1 is routed to PCI function 0. This bit is
mapped to FACTPS[30].
Reserved.
Disables the PCIe completion timeout mechanism.
This bit is mapped to GCR.Completion_Timeout_Disable.
0b = Completion timeout enabled.
1b = Completion time out disabled.
Determines the range of the PCIe completion timeout.
00b = 0.5 ms to 1 ms.
01b = 50 ms to 100 ms.
10b – 0.5 s to 1 s.
11b = 10 s to 20 s.
When set, enables a response to a request once the completion timeout
expired.
This bit is mapped to GCR.Completion_Timeout_Resend.
0b = Do not resend request on completion timeout.
1b = Resend request on completion timeout.
Enables support for dummy function when only Function is needed.
0b = Disable.
1b = Enable.
Enables the use of the wake pin for a PME event in all power states.
LAN PCI Disable
When set to 1b, one LAN port is disabled and the appropriate PCI function
might be disabled and act as a dummy function.
The function that is disabled is determined by the LAN PCI Function Select
field. If the disabled function is function 0, it acts as a dummy function.
LAN Disable Select
0b = LAN 0 is disabled.
1b = LAN 1 is disabled.
