TC/VC0 Map
Indicates the TCs (Traffic Classes) that are mapped to the VC resource. Bit locations
within this field correspond to TC values. For example, when bit 7 is set in this field,
TC7 is mapped to this VC resource. When more than one bit in this field is set, it
indicates that multiple TCs are mapped to the VC resource. In order to remove one
or more TCs from the TC/VC Map of an enabled VC, software must ensure that no
new or outstanding transactions with the TC labels are targeted at the given Link.
TC0/VC0 Map
Traffic Class 0 is always routed to VC0.
Reserved
VC0 Negotiation Pending
0: The VC negotiation is complete.
1: The VC resource is still in the process of negotiation (initialization or disabling).
This bit indicates the status of the process of Flow Control initialization. It is set by
default on Reset, as well as whenever the corresponding Virtual Channel is Disabled
or the Link is in the DL_Down state. It is cleared when the link successfully exits the
FC_INIT2 state
Before using a Virtual Channel, software must check whether the VC Negotiation
Pending fields for that Virtual Channel are cleared in both Components on a Link.
