Hi 
 the generator polynomial for the crc-32Q (32 31 24 22 16 14 8 7 5 3 1 0) as
given in Appendix A is reducable, as I tried it on the internet on a
CRC-calculator tool. 
The ethernet polynomial which is 
  (32 26 23 22 16 12 11 10 8 7 5 4 2 1 0)   is not reducable.
 Now as per my understanding reducable polynomial is not better than the
irreducable one. 
 If reducable one is not good, why did we choose crc-32Q polynomial instead
of crc-32 polynomial(used for ethernet)?

Can somebody please explain it to me.

Regards and Thanks
