Wiring SPI module to Beaglebone Black
Simple enough. Pins 1 is the SPI Chip Select (GPIO). 2 - 4 are SPI data and clock pins. RST is an active low input (to the ENC28J60) so any GPIO can be used. INT and WOL are active low outputs (from the enc), so a GPIO in input mode on the BeagleBone.

For the SPI pins, you want the p9 header pins 28-31, which are Chip Select, Data Out, Data In, Clock. Any GPIO will work for the other signals.
