param: Add dev_add_param_mac ...

This adds a convenience function to register a MAC address device
parameter. The only current user is converted to use it.

netconsole: bail out when no connection is opened ...

When no connection is opened we should not call into
the networking stack. Otherwise it can happen that we
delay further execution until the network stack detected
a link (or timed out bringing the link up).

net: Add ifup support ...

The defaultenv-2 has ifup support as a shell script. This patch
replaces it with a command which is more robust, can be called
from C and now can also bring up all configured interfaces.

Otherwise we loose memory on each device_unregister. The ethernet
code used to do this before calling unregister_device. This can
now be removed.

If drivers want to fixup their specific instance they need some context

net, of: fixup MAC address by alias ...

If a network device has not been registered from the devicetree, we may
still find it by its alias in the devicetree. This way also platform based
network devices can obtain a valid MAC address in the devicetree.

net: fix checksum verification ...

Checksum calculation on data including its own checksum (as is the case with
IP headers) should give 0xffff before bit flipping. Current code works well
for the correct checksum case, but fails to identify errors.

eth_of_fixup() is passed a devicetree, so use this one instead
of the internal devicetree. This makes sure it also works when
the tree to fixup is not the internal one.

net: Set mac-address property ...

Linux normally has no idea how to retrieve MAC Addresses, but instead
expects the MAC address in the devicetree. This patch adds the MAC
address to the devicetree for Linux if we find a valid one in barebox.
This mechanism is limited of course to devices barebox has a driver for
and which are probed themselves from the devicetree.

net: Add of_register_ethaddr ...

We already have a possibility to register a MAC address provider
based on a ethernet device id. This adds a similar functionality
for devices probed from devicetree. Code can register itself to
be a MAC address provider for a certain devicetree node.

This helps on i.MX to let the IIM unit provide a MAC address for
the FEC.

net: dhcp: Fix tftp servername handling ...

When the dhcp code discovered the tftp-server-name option it immediately
tries to resolve the name. This can't succeed since the we are somewhere
in the dhcp processing and the nameserver may not even be known.

Fix this by resolving the name when dhcp is completed. While at it, do
this in a way that net_set_serverip is only called when resolv() returns
something useful. Otherwise we may end up overwriting a previously
configured serverip which came from the bootp bp_siaddr field.
