 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

The adapter counter lock word serializes the field NICNCABK, the contents of the NCABK, and the adapter counters (starting with NICCTRS).

Notes : LKWRDSIZ == 3 doublewords. 00E0 224 Dbl-Word 8 NICCTRLK (3) Adapter Counter Lockword NICCCLBK is a pointer to the Counters Clear Block CCLBK. 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. This pointer and the CCLBK structure are serialized by the Adapter Counter Lockword (NICCTRLK). 00F8 248 Address 4 NICCCLBK Pointer to CCLBK-Counters clear Adapter Counters 0100 256 Dbl-Word 8 NICCTRS (0) Start of NICBK counters The following set of counters are used to keep track of a specific port's attempt to acquire key locks or queue 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 (LANLKWRD) lock requests sending or receiving data. NICBK (NICLKWRD) lock requests when sending data to another port. NICBK (NICLKWRD) lock requests when receiving data from another port.

Adapter Transmit and Receive Counters Counters are maintained on a queue basis - one set for Transmit (output) and one set for Receive (input). The number of input and output queues can vary based on the port represented by this NIC. Most ports will have 1 input queue and 1 output queue. A UPLINK device will have 1 input queue and either 1, 2, or 4 output queues. If a VSwitch is configured for PRIQUEUING ON and the UPLINK device has PQ_ON, then 4 output queues are created. For the IVL VSwitch with PRIQUEUING ON and the device has PQ_ON, then 2 output queues are created. All other UPLINK devices will have 1 input queue and 1 output queue. **** RECALL that the counters are maintained in the NICBK **** from the perspective of the simulated LAN segment. For **** an UPLINK NIC, this means it is the RX counters that **** represent the output queues. -- For simplicity sake, 1 set of NICTX counters and 4 -- sets of NICRX counters are included/allocated here, -- although is only a VSwitch UPLINK device that will -- ever reference more than 1 NICRX set.

It is serialized by the BPBCFGLK which ensures only one Bridge Port Configuration change is being handled at a time and allows the safe increment/decrement of NICBCFGC without holding the NICLKWRD lock. This counter is used when deciding whether a Logical Guest Port can be removed when there are no longer any MACs or VLANs associated with the port. If there are still pending changes (NICBCFGC>0) then new/additional MACs may be in the queue to be added and therefore the port should not be removed. The counter should be incremented before stacking a call to HCPSWFNC to add/delete a MAC or VLAN for the HS logical guest port. HCPSWFNC will decrement the count as it processes the change. 0236 566 Signed 2 NICBCFGC Configuration Count 0238 568 Signed 4 * Reserved for Future IBM Use Attributes from the NICDEF command.
