VC1 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.
