Hello all,
I'm working with the FEC driver for MPC5777M.
I've trouble with the hash table generation because my crc32 computation does not give the same result as the one given in the following thread : https://community.nxp.com/message/881095
Strange since I use the common CRC32 for ethernet with the same polynom.
There is very few information about hash table computation in the reference manual. When the RM will be updated or is there any application note that I can read ?
Anyway, I've tried then to use the same algorithm as you for multicast and unicast filtering and it works fine.
What is the maximum size of a group (number of possible destinations addresses ) in multicast ? Is it 256 possible destinations ?
For example, is it possible to enable addresses from 65 00 00 00 00 00 to 65 FF FF FF FF FF ?
Is it possible to limit the number of destinations addresses within a group (for example 16) ?
Best regards.
Paulo
