 * driver for homePNA PHYs
 * This is really just a stub that allows us to identify homePNA-based
 * transceicers and display the link status. MII-based homePNA PHYs
 * only support one media type and no autonegotiation. If we were
 * really clever, we could tweak some of the vendor-specific registers
 * to optimize the link.
