Martin Stein fa64aae7f8 nic_router: config attribute 'dns_config_from'
WARNING: BREAKS CONFIG COMPATIBILITY!

This commit changes the configuration interface of the NIC router in a way that
may break systems that use the component without proper adjustment!

How to adjust:
At each occurrence of the 'dns_server_from' attribute in a NIC router
configuration replace the attribute name with 'dns_config_from'. The attribute
value remains unaltered.

DETAILED DESCRIPTION

The new attribute name 'dns_config_from' reflects that also other aspects of
the DNS configuration of the denominated domain are used by the DHCP server
that holds the attribute. This commit is a preparation for forwarding also the
domain name (DHCP option 15) with the mechanism behind the attribute.

# \brief Test for using the lwIP TCP/IP stack
# \author Norman Feske
# \date 2011-05-22
#
# This test case executes a small HTTP server on Genode running on qemu. When
# the HTTP server is up, a HTTP request to the server is performed using
# 'lynx'. The response is validated against a known pattern.
#
# The test uses qemu's "-netdev user" option, redirecting Genode's port 80 to the
# host's port 5555. Consequently, it cannot be executed on non-qemu test
# environments (i.e., the test won't work with the Linux version of Genode).
#
# Please make sure to include a nic driver in your build configuration. E.g.,
# on the x86 platform, you may enable the 'dde_ipxe' repository.
#
#
# TODO: Add support for Linux via user-level networking (using the
# tun/tap proxy driver at os/src/drivers/nic/linux)
