+/*
+ * Description: This VNIC is a resource in the RX side of the chip that is used
+ * to represent a virtual host "interface". # At the time of VNIC allocation or
+ * configuration, the function can specify whether it wants the requested VNIC
+ * to be the default VNIC for the function or not. # If a function requests
+ * allocation of a VNIC for the first time and a VNIC is successfully allocated
+ * by the HWRM, then the HWRM shall make the allocated VNIC as the default VNIC
+ * for that function. # The default VNIC shall be used for the default action
+ * for a partition or function. # For each VNIC allocated on a function, a
+ * mapping on the RX side to map the allocated VNIC to source virtual interface
+ * shall be performed by the HWRM. This should be hidden to the function driver
+ * requesting the VNIC allocation. This enables broadcast/multicast replication
+ * with source knockout. # If multicast replication with source knockout is
+ * enabled, then the internal VNIC to SVIF mapping data structures shall be
+ * programmed at the time of VNIC allocation.
