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