NAME : HCPNCABK
DESCRIPTION: Network Card Accounting Block.
DSECT : NCABK
FUNCTION :
This structure contains accounting information for
a fully-simulated Network Interface Card (NIC).
LOCATED BY :
NICNCABK - Pointer to NCABK (when accounting is enabled)
CREATED BY :
COUPLE processing when the adapter is connected to a
VM LAN segment with ACCOUNTING enabled.
SET LAN processing when the adapter is connected to a
VM LAN segment for which ACCOUNTING is being enabled.
DELETED BY :
UNCOUPLE processing when the adapter is disconnected
from a VM LAN segment with ACCOUNTING enabled.
SET LAN processing when the adapter is connected to a
VM LAN segment for which ACCOUNTING is being disabled.
REFERENCES : none.
SERIALIZED :
Adapter Counter Lock (NICCTRLK) must be held EXCLUSIVE
to update these fields.
Adapter Counter Lock (NICCTRLK) must be held SHARED
to safely reference these fields.
RELOCATION CONSIDERATIONS : None
COMPATIBILITY AND MIGRATION CONCERNS : None.
