This is a collections of user-level programs to report the status of and verify the basic functionality of an ethercard.
Most programs report the link status and interface configuration.
These program also provide example code for accessing hardware device from a user-level program in Linux. The PCI diagnostic programs demonstrate user-level access to PCI configuration information. The 'mii-diag' program reports the link status. It works with most of the Fast Ethernet device drivers. The link status may be monitored by non-root users, with root or network administration privileges required to modify the transceiver settings.
