[PATCH] linkstate: Add macros for link state up/down

[Olliver Schinagl]

The phylink_link_state.state property can be up or down, via 1 and 0.

The other link state's (speed, duplex) are defined in ethtool.h so lets
add defines for the link-state there as well so we can use macro's to
define our up/down states.
