# \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 "-net 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.
#

#       tun/tap proxy driver at os/src/drivers/nic/linux)
