Yes. I know of 3 datasheets from National Semiconductor,

11719  DP83934CVUL-20/25 MHz SONIC-T Systems-Oriented Network Interface
Controller with Twisted Pair Interface
10492  DP83932C-20/25/33 MHz SONIC Systems-Oriented Network Interface
Controller
11722  DP83916 SONIC-16 Systems-Oriented Network Interface Controller

The publication numbered 10492 is the one that Laurent linked to. It and
11722 both have the same table of contents. The references I gave in the
patch descriptions are applicable to these. (Having said that, I see now
that I did mess up one reference. I'll fix it.)

The "1995 National Ethernet Databook" on bitsavers has more information.
