The apps note page has a link to the PDF and Linux drivers ... but the drivers are a kernel module .ko module only. The PDF provides details on the driver source location (on rocketboards.org).

Perhaps this is sufficient for what you were interested in doing ... personally I'd prefer to see a document with the protocol published.

Perhap the driver source code is sufficient for what you want. It is possible that the driver just forwards the content of Ethernet packets down to the JTAG chain. Wireshark would allow you to see the Ethernet packet format.

Chances are the SLD HUB protocol has not changed much from the JTAG-only version ... scroll down to the JTAG-to-Avalon-MM/ST and Virtual JTAG analysis docs:
