NAME       : HCPCCLBK
 DESCRIPTION: VSwitch Counter Block
 DSECT      : CCLBK
 FUNCTION   :
              Each structure contains time-stamps and transmission
              counters associated with NIC for reset counter support.
 LOCATED BY :
              NICCCLBK = Pointer to counters clear structure
 CREATED BY :
              SET VSWITCH COUNTERS CLEAR processing (module HCPSWS)
 DELETED BY :
              CP DETACH NIC command processing (module HCPNIC)
              CP DETACH LAN command processing (module HCPVLF)
              VSWITCH connect processing (modules HCPVLC, HCPSWG and
              and HCPNDF)
 RELOCATION CONSIDERATIONS : None
 SERIALIZED : This control block (NICCCLBK) is serialized by the NIC
              Adapter Counter Lock:
              - Hold NICCTRLK exclusive to add or remove control block
              The fields in this control block are used during QUERY
              VSWITCH and QUERY NIC calls.  These fields are serialized
              by the NIC Adapter Counter Lock:
              - Hold NICCTRLK exclusive to update
              - Hold NICCTRLK shared to reference

      This control block is created when SET VSWITCH COUNTERS
      CLEAR {DATA|ERRORS|DISCARDED|ALL} is called.
      The control block contains timestamps for DATA, ERRORS
      and DISCARDED.  It also contains delta values for the
      counter values (errors, discarded, transmitted packets,
      transmitted bytes, received packets and received bytes).
      The delta values will be used when calculating
      the correct values to be displayed by the QUERY commands.
