- Manages the multicast receive filters of a network interface.
-
- @param This The protocol instance pointer.
- @param Enable A bit mask of receive filters to enable on the
- network interface.
- @param Disable A bit mask of receive filters to disable on the
- network interface.
- @param ResetMCastFilter Set to TRUE to reset the contents of the multicast
- receive filters on the network interface to their
- default values.
- @param McastFilterCnt Number of multicast HW MAC addresses in the new
- MCastFilter list. This value must be less than or
- equal to the MCastFilterCnt field of
- EFI_SIMPLE_NETWORK_MODE. This field is optional if
- ResetMCastFilter is TRUE.
- @param MCastFilter A pointer to a list of new multicast receive filter
- HW MAC addresses. This list will replace any
- existing multicast HW MAC address list. This field
- is optional if ResetMCastFilter is TRUE.
-
- @retval EFI_SUCCESS The multicast receive filter list was updated.
- @retval EFI_NOT_STARTED The network interface has not been started.
- @retval EFI_INVALID_PARAMETER One or more of the parameters has an
- unsupported value.
- @retval EFI_DEVICE_ERROR The command could not be sent to the network
- interface.
- @retval EFI_UNSUPPORTED This function is not supported by the network
- interface.
