What is filterSourceMask?

This read-write OCTET STRING is a bitmask applied to a packet's source address before comparing it against the filterSource/filterSourceEnd range. An admin uses this to ignore certain bits of the source address during matching, for example to match only on a vendor prefix rather than the full unique address. Setting filterSourceMask to mask out the host-specific bits lets the filter match any device from a given manufacturer regardless of its individual MAC suffix.
