mii_check_media - check the MII interface for a duplex change : the MII interface : OK to print link up/down messages : OK to save duplex mode in

Returns 1 if the duplex mode changed, 0 if not. If the media type is forced, always returns 0.

mii_nway_result : value of MII ANAR and'd with ANLPAR

Given a set of MII abilities, check each bit and returns the currently supported media, in the priority order defined by IEEE 802.3u. We use LPA_xxx constants but note this is not the value of LPA solely, as described above.

The one exception to IEEE 802.3u is that 100baseT4 is placed between 100T-full and 100T-half. If your phy does not support 100T4 this is fine. If your phy places 100T4 elsewhere in the priority order, you will need to roll your own function.

mii_duplex : Non-zero if duplex is locked at full : value of MII ANAR and'd with ANLPAR

A small helper function for a common case. Returns one if the media is operating or locked at full duplex, and returns zero otherwise.
