TM4C1294NCPDT datasheet says it only has 4 SSI interfaces.
http://www.ti.com/lit/ds/symlink/tm4c1294ncpdt.pdf (datasheet) lists all the pins and functions, and indeed it lists SSI2, SSI3, SSI0, SSI1 as does the User Guide for the LaunchPad, http://www.ti.com/lit/ug/spmu365a/spmu365a.pdf.
Leads me to belive SPI5 is a typo.

The TM4C1294NCPDT features a MAC/PHY. The communication to the MAC is through registers directly. There are no physical pins involved other than the pins connected to the Ethernet transformer but these are dedicated pins and not GPIO's/SPI.
