__rte_experimentalintrte_pmd_dlb2_set_token_pop_mode(uint8_tdev_id,uint8_tport_id,enumdlb2_token_pop_modemode)WarningEXPERIMENTAL: this API may change, or be removed, without prior notice

       Configure the token pop mode for a DLB2 port. By default, all ports use AUTO_POP. This function must be
       called before calling rte_event_port_setup() for the port, but after calling rte_event_dev_configure().

       Parametersdev_id The identifier of the event device.
           port_id The identifier of the event port.
           mode The token pop mode.

       Returns

           • 0: Success

           • EINVAL: Invalid dev_id, port_id, or mode

           • EINVAL: The DLB2 is not configured, is already running, or the port is already setup

#defineRTE_PMD_DLB2_GET_QID_DEPTH(x)((x)->rsvd&0x3)
       Macro function to get QID depth of rte_event metadata. Currently lower 2 bits of 'rsvd' field are used to
       store QID depth.

       Definition at line 26 of file rte_pmd_dlb2.h.

   #defineRTE_PMD_DLB2_SET_QID_DEPTH(x,v)((x)->rsvd=((x)->rsvd&~0x3)|(v&0x3))
       Macro function to set QID depth of rte_event metadata. Currently lower 2 bits of 'rsvd' field are used to
       store QID depth.

       Definition at line 32 of file rte_pmd_dlb2.h.

   #defineRTE_PMD_DLB2_GET_QE_WEIGHT(x)(((x)->rsvd>>2)&0x3)
       Macro function to get QE weight from rte_event metadata. Currently upper 2 bits of 'rsvd' field are used
       to store QE weight.

       Definition at line 38 of file rte_pmd_dlb2.h.

   #defineRTE_PMD_DLB2_SET_QE_WEIGHT(x,v)((x)->rsvd=((x)->rsvd&0x3)|((v&0x3)<<2))
       Macro function to set QE weight from rte_event metadata. Currently upper 2 bits of 'rsvd' field are used
       to store QE weight.
