Support for the PHYsical layer chip in ForeRunner LE25 cards. In
addition to cable removal/reinsertion detection, this driver allows
you to control the loopback mode of the chip via a dedicated IOCTL.
This driver is required for proper handling of temporary carrier
loss, so if you have a 25Mbps NICStAR based ATM card you must say Y.
