cfgFilterNetworkMask

This is the wild card mask for the 
cfgFilterNetworkAddress bits that must match.
Presence of 0 bits in the mask indicate that
corresponding bits in the cfgFilterNetworkAddress 
must match in order for the matching to be successful,
and 1 bits are don't care bits in the matching.
A value of zero causes only IP packets of source
and destination address the same as 
cfgFilterNetworkAddress to match.  
This object value has to be consistent with the type 
specified in cfgFilterNetworkAddressType.
