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 link.
