Virtual Channel 1 Negotiation Pending (VC1NP)
0 = The VC negotiation is complete.
1 = The VC resource is still in the process of negotiation 
(initialization or disabling).
Software may use this bit when enabling or disabling the VC. This 
bit indicates the status of the process of Flow Control initialization. 
It is set by default on Reset, as well as when 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.
