net: neighbor: add fdb extended attribute
Add an attribute to NDA which will contain all future fdb-specific
attributes in order to avoid polluting the NDA namespace with e.g.
bridge or vxlan specific attributes. The attribute is called
NDA_FDB_EXT_ATTRS and the structure would look like:
[NDA_FDB_EXT_ATTRS] = {
[NFEA_xxx]
}
