     NAME       : HCPNICBK
     DESCRIPTION: Virtual Network Interface Card block
     DSECT      : NICBK
     FUNCTION   :
                  Define a structure to represent a Network Interface
                  Card.  One NICBK exists for each Virtual Adapter.
                  Each NICBK is associated with a set of Virtual
                  Network Interface Devices (VDEV/NIDBK).
     LOCATED BY -
       VDEVNIC  = Pointer to owning adapter NICBK
       NIDNICBK = Pointer to owning adapter NICBK
       LNKNICHD = Pointer to chain of coupled adapter NICBK

          Static Area -
            The fields in this area are relatively constant.
            They are initialized when the adapter (NIC) is
            created, and may be referenced with minimal
            serialization (just enough to be sure your pointer
            to the NICBK is valid).

          NICVLANS represents the Authorized VID set.
            When NICVLANS==NULL it means the switch simulation
              does not restrict the virtual NIC to any specific
              VID set.
            When NICVLANS==nonzero it points to the DVLHEAD
              structure representing the Authorized VID set for
              this virtual NIC on this virtual switch.

          Adapter Management Area -
            The fields in this area are used in the normal
            operation of the adapter (NIC).  In general,
            these fields are serialized by the NIC Adapter Lock:
            - Hold NICLKWRD EXCLUSIVE to update
            - Hold NICLKWRD SHARED to reference
          NICRFCTR is used to protect the NICBK over a stacked call.
          - NICRFCTR is updated using Compare and Swap (CS) logic.
          - NICLKWRD (Shared or Exclusive) must be held, or
            LANLKWRD (Shared or Exclusive) must be held to update
            NICRFCTR.
          - The code that intends to initiate a deferred (stacked)
            call must increment NICRFCTR (using CS logic).
          - The code that is dispatched asynchronously should
            perform the following steps:
            (1) Obtain NICLKWRD (Shared or Exclusive)
            (2) Decrement NICRFCTR (using CS logic).
            (3) If NICDLPRG=1 (Delete in Progress),
                   If NICRFCTR = 0,
                      Obtain NICLKWRD Exclusive (see HCPLCKSX).
                      Call HCPNICDX to Destroy this NICBK.
                      Exit without attempting to release NICLKWRD.
                   If NICRFCTR > 0,
                      Release NICLKWRD and exit.

          LAN Management Area -
            The fields in this area are used to connect the
            adapter (NIC) to a Virtual LAN.
            To connect or disconnect this adapter (NIC) to/from
            a Virtual LAN, the following locks must be obtained
            (in this sequence):
            - The LAN Lock (LANLKWRD) EXCLUSIVE
            - The NIC Adapter Lock (NICLKWRD) EXCLUSIVE
            To reference these fields (e.g. while following
            the chain) you only need to hold LANLKWRD SHARED.
            - Access to the field NICNCABK and the contents of
              the NCABK are serialized by the NICCTRLK.

          Adapter Counters (Continue)
          The following set of counters are used to keep track of a
          specific port's attempt to acquire key locks or stack work
          in the main line data transfer path.  In addition to
          keeping track of the lock requests, a corresponding
          counter will indicate the number of times the port had to
          wait to perform the function.
          The following information is kept on a per port basis,
          including both real and virtual guest LAN ports:
            LANBK (LANLKWR) lock requests sending or receiving data.
            NICBK (NICLKWD) lock requests when sending data to
                            another port.
            NICBK (NICLKWD) lock requests when receiving data from
                            another port.
