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 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.
