Its a shame that Ubiquiti, who after all ship Openwrt with their board, can not be prevailed upon to provide some information. Over time I have accumulated three adm6996 datasheets, one for the L variant, one for M and one for F (but not FC). The M one is vast (7MB), but the F is small (700K) and the L 1.7M. I can email them to you direct if you want as I suspect the list would not appreciate them being broadcast. I have no idea where I got them from although none are marked confidential so they should be freely distributable.
