Dear all,
The Ethernet protocol RAM area structure defined in include/asm/cpm_8260.h is taking 8 bytes of additional space due to "ushort rfthr" and "ushort rfcnt". These are not part of FEC parameter RAM area as per the MPC8260 / MPC8280 datasheet.Also as per the data sheet the size of the FCC (Ethernet) parameter area can be only 0xFF, due to these parameters the size is greater than 0xFF by 8 bytes.
Just wanted to know was there any consideration for putting these fields in the FEC parameter RAM area or is it a mistake? Thanks for your understanding.
With Regards,
C.R.Srivatsan
