-  This function updates the SNP driver status.
-
-  This function gets the current interrupt and recycled transmit
-  buffer status from the network interface.  The interrupt status
-  and the media status are returned as a bit mask in InterruptStatus.
-  If InterruptStatus is NULL, the interrupt status will not be read.
-  Upon successful return of the media status, the MediaPresent field
-  of EFI_SIMPLE_NETWORK_MODE will be updated to reflect any change
-  of media status.  If TxBuf is not NULL, a recycled transmit buffer
-  address will be retrived.  If a recycled transmit buffer address
-  is returned in TxBuf, then the buffer has been successfully
-  transmitted, and the status for that buffer is cleared.
-
-  This function calls ::Ax88772Rx to update the media status and
-  queue any receive packets.
-
-  @param [in] pSimpleNetwork    Protocol instance pointer
-  @param [in] pInterruptStatus  A pointer to the bit mask of the current active interrupts.
-                                If this is NULL, the interrupt status will not be read from
-                                the device.  If this is not NULL, the interrupt status will
-                                be read from teh device.  When the interrupt status is read,
-                                it will also be cleared.  Clearing the transmit interrupt
-                                does not empty the recycled transmit buffer array.
-  @param [out] ppTxBuf          Recycled transmit buffer address.  The network interface will
-                                not transmit if its internal recycled transmit buffer array is
-                                full.  Reading the transmit buffer does not clear the transmit
-                                interrupt.  If this is NULL, then the transmit buffer status
-                                will not be read.  If there are not transmit buffers to recycle
-                                and TxBuf is not NULL, *TxBuf will be set to NULL.

-/**
-  This function is used to enable and disable the hardware and software receive
-  filters for the underlying network device.
-
-  The receive filter change is broken down into three steps:
-
-    1.  The filter mask bits that are set (ON) in the Enable parameter
-        are added to the current receive filter settings.
-
-    2.  The filter mask bits that are set (ON) in the Disable parameter
-        are subtracted from the updated receive filter settins.
-
-    3.  If the resulting filter settigns is not supported by the hardware
-        a more liberal setting is selected.
-
-  If the same bits are set in the Enable and Disable parameters, then the bits
-  in the Disable parameter takes precedence.
-
-  If the ResetMCastFilter parameter is TRUE, then the multicast address list
-  filter is disabled (irregardless of what other multicast bits are set in
-  the enable and Disable parameters).  The SNP->Mode->MCastFilterCount field
-  is set to zero.  The SNP->Mode->MCastFilter contents are undefined.
-
-  After enableing or disabling receive filter settings, software should
-  verify the new settings by checking the SNP->Mode->ReceeiveFilterSettings,
-  SNP->Mode->MCastFilterCount and SNP->Mode->MCastFilter fields.
-
-  Note: Some network drivers and/or devices will automatically promote
-  receive filter settings if the requested setting can not be honored.
-  For example, if a request for four multicast addresses is made and
-  the underlying hardware only supports two multicast addresses the
-  driver might set the promiscuous or promiscuous multicast receive filters
-  instead.  The receiving software is responsible for discarding any extra
-  packets that get through the hardware receive filters.
-
-  If ResetMCastFilter is TRUE, then the multicast receive filter list
-  on the network interface will be reset to the default multicast receive
-  filter list.  If ResetMCastFilter is FALSE, and this network interface
-  allows the multicast receive filter list to be modified, then the
-  MCastFilterCnt and MCastFilter are used to update the current multicast
-  receive filter list.  The modified receive filter list settings can be
-  found in the MCastFilter field of EFI_SIMPLE_NETWORK_MODE.
-
-  This routine calls ::ReceiveFilterUpdate to update the receive
-  state in the network adapter.
-
-  @param [in] pSimpleNetwork    Protocol instance pointer
-  @param [in] Enable            A bit mask of receive filters to enable on the network interface.

-                                For backward compatibility with EFI 1.1 platforms, the
-                                EFI_SIMPLE_NETWORK_RECEIVE_MULTICAST bit must be set
-                                when the ResetMCastFilter parameter is TRUE.
-  @param [in] bResetMCastFilter Set to TRUE to reset the contents of the multicast receive
-                                filters on the network interface to their default values.
-  @param [in] MCastFilterCnt    Number of multicast HW MAC address in the new MCastFilter list.
-                                This value must be less than or equal to the MaxMCastFilterCnt
-                                field of EFI_SIMPLE_NETWORK_MODE.  This field is optional if
-                                ResetMCastFilter is TRUE.
-  @param [in] pMCastFilter      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.
