> -
> -    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

> -
> -  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.
