- 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.
