ifstatus is an utility which may be used to detect the link status of a local Linux ethernet device, much in the same way mii-diag, mii-tool and ethtool work. In fact it supports all three different APIs these three tools use. Thus, it provides maximal compatibility. The newest API (ethtool) is used first, than the next older (mii-diag) and at last the oldest (mii-tool). It may be used in shell script since it returns the current status as return value. It is especially useful to detect the available APIs on the used network driver. (Option -v)
