Device Control Operations

The ndd_ctl entry point is used to provide device control functions.

NDD_GET_STATS Device Control Operation
The NDD_GET_STATS command returns statistics concerning the network device. General statistics are maintained by the device driver in the ndd_genstats field in the ndd_t structure.
NDD_MIB_QUERY Device Control Operation
NDD_MIB_GET Device Control Operation
The NDD_MIB_GET operation is used to get all MIBs on the specified network device. The arg and length parameters specify the address and length in bytes of the device specific MIB structure. The device driver sets any unsupported variables to zero (nulls for strings).
NDD_ENABLE_ADDRESS Device Control Operation
The NDD_ENABLE_ADDRESS command enables the receipt of packets with an alternate (for example, multicast) address. The arg and length parameters specify the address and length in bytes of the alternate address to be enabled. The NDD_ALTADDRS flag in the ndd_flags field is set.
NDD_DISABLE_ADDRESS Device Control Operation
The NDD_DISABLE_ADDRESS command disables the receiving packets with a specified alternate (for example, multicast) address. The arg and length parameters specify the address and length in bytes of the alternate address to be disabled. The NDD_ALTADDRS flag in the ndd_flags field is reset if this is the last alternate address.
NDD_MIB_ADDR Device Control Operation
The NDD_MIB_ADDR operation is used to get all the addresses for which the specified device accepts packets or frames.
NDD_CLEAR_STATS Device Control Operation
The counters kept by the device are zeroed.
NDD_GET_ALL_STATS Device Control Operation
The NDD_GET_ALL_STATS operation is used to gather all the statistics for the specified device.
NDD_ENABLE_MULTICAST Device Control Operation
The NDD_ENABLE_MULTICAST command enables the receipt of packets with any multicast (or group) address.
NDD_DISABLE_MULTICAST Device Control Operation
The NDD_DISABLE_MULTICAST command disables the receipt of all packets with multicast addresses and only receives those packets whose multicast addresses were specified using the NDD_ENABLE_ADDRESS command.
NDD_PROMISCUOUS_ON Device Control Operation
The NDD_PROMISCUOUS_ON command turns on promiscuous mode. The arg and length parameters are not used.
NDD_PROMISCUOUS_OFF Device Control Operation
The NDD_PROMISCUOUS_OFF command terminates promiscuous mode.
NDD_DISABLE_ADAPTER Device Control Operation
The NDD_DISABLE_ADAPTER operation is used by Etherchannel to disable the adapter so that it cannot transmit or receive data.
NDD_ENABLE_ADAPTER Device Control Operation
The NDD_ENABLE_ADAPTER operation is used by Etherchannel to return the adapter to a running state so it can transmit and receive data. During this operation the adapter is started and the NDD_RUNNING flag is set.
NDD_SET_LINK_STATUS Device Control Operation
The NDD_SET_LINK_STATUS operation is used by Etherchannel to pass the driver a function pointer and argument that will subsequently be called by the driver whenever the link status changes.
NDD_SET_MAC_ADDR Device Control Operation
The NDD_SET_NAC_ADDR operation is used by Etherchannel to set the adapters MAC address at runtime.
