iSCSI: CRC32C Table generation

["Lakshmi Ramasubramanian" <nramas@windows.microsoft.com>]

In the code given in RFC-1952 for generating the table
for CRC32 algorithm, the constant 0xedb88320 is used.
Since this constant is derived from the polynomial,
it's different than 0xedb88320 for iSCSI. It took
some effort to find out the steps to arrive at the constant
from the given CRC32 polynomial. 

May I suggest we include this conversion steps in an appendix 
in the spec? 

thanks!
