[PATCH] natsemi update 2/4 Ethtool ioctl fixes & enhancements

Jeff,

This is the second of a series of patches needed to support our product using the DP83815.

This patch fixes some of the ethtool ioctl support.  It does a better job of switching autonegotiation/speed/duplex parameters.  It no longer reports failure to complete negotiation when auto negotiation was disabled.  Attempts to return the MII registers from the MII interface, rather than always using the internal registers.  Formally set PORT_MII as XCVR_EXTERNAL and PORT_TP as XCVR_INTERNAL.
