We call phy_update_status only once in 5 seconds. This makes
sure we do not have great overhead when using ethernet devices.
However, if phylib tells us the link is down anyway, there won't
be ethernet transfers, so it doesn't hurt to call phy_update_status
in this case. This makes sure we can use the ethernet device when
the link comes up and do not have an additional 5 second penalty
in this case.

edev->init is called at eth_register time unconditionally and is supposed
to initialize the ethernet hardware. Since it's called unconditionally
this could be done by the driver without having an additional hook.
Some drivers need their initialization done earlier since they also register
a mdiobus which does hardware accesses on registration time.

Adapt phylib from linux
switch all the driver to it
reimplement mii bus
This will allow to have
- phy drivers
- to only connect the phy at then opening of the device
- if the phy is not ready or not up fail on open
Same behaviour as in linux and will allow to share code and simplify porting.

The FSF address has changed in the past. Instead of updating it
each time the address changes, just drop it completely treewide.

We register a device in eth_register, thus we have to unregister it in
eth_unregister. Also, if the device we unregister is the current device,
we have to set the current eth_device to NULL so that it isn't used anymore.

MAC addresses are sometimes stored at unusual places. This
patch makes it possible to give a MAC address to a ethernet
device id. This is independent of the device actually being
present.

When retrieving the MAC address from EEPROM, we must notify the networking core
at eth registration time. Otherwise we get the 'No MAC address set' warning on
the first network access, and the MAC address is set to a random value instead
of the real one.

Change device parameters so that the memory management is in generic
code. This also removes the need of storing statically initialized
parameters as they are stored in a struct list_head for each device.

We used to eth_open/eth_halt the network devices during NetLoopInit
which is called whenever the user enters a network command.
Change this behaviour so that the current network device gets opened
when making it the current one.
With this change it's always possible to send packages and we are able
to implement a new network stack in the next step.

Instead of writing the MAC address into the hardware on device open time
write it to the hardware when the user changes the parameter. This
way a user can change the MAC address in the hardware without actually
using the device. This helps Linux Network drivers which expect a valid
MAC address on startup.
