+/**
+ 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.
+ @param [in] Disable A bit mask of receive filters to disable 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.
