Enhanced buffer descriptors for iMX6Q

Can anyone point me to a description of the Enhanced Buffer Descriptors for the Ethernet Controller on an iMX6Q?  Section 23.6.14 of the reference manual is missing (i.MX 6Dual/6Quad Applications Processor Reference Manual, Rev. 2, 06/2014).  The reference manual for the Solo has a description of the legacy buffers, but not the enhanced.

 

Side question: We are developing a system sans Linux (uCOS) and are having a few issues surrounding errata ERR004512.  Does anyone knows of a handy app note or reference for the settings of the RX FIFO levels/pause frame configurations?
