Address hashing in FEC

I'm now initializing the FEC in my MCF5270 and am a bit puzzled by the Hash tables' configuration.
 
I think the explanation is clear enough, but am I correct in assuming that the table of MAC addresses and their coresponding hashes (Table 19-36, p. 19-43, MCF5271RM) is totally without value to me, except perhaps for validating my own algorithm?
 
As I read it, the only way to correctly configure this table is to write my own CRC32 algorithm, just to generate the 6-bit hash.  Is there some way I can leverage the hardware CRC generator for this?
 
TIA
