Reserved
Virtual Channel 0 Negotiation Pending (VC0NP)
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 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.
BIOS Requirement: 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.

applicable but is not Set within the TLP Header will be rejected
as an Unsupported Request.

Having only bit 0 set indicates that the only supported arbitration
scheme for this VC is non-configurable hardware-fixed.
