This kernel module creates the
/sys/devices/platform/mts-io enumeration
of the features for MTAC ETH boards.

This driver requires the mtac.ko driver
loaded first.  depmod should take care
of this.

Documentation for this board is here:

http://www.multitech.net/developer/software/mlinux/using-mlinux/mlinux-using-accessory-cards/mtac-eth-usage/

An init script can look in:
/lib/modules/$(uname -r)/extra/mtac_xdot.ko

to find the driver.
