Using the Build->Packages dialog, +add the packages “Networking”, +“OpenBSD TCP/IP Stack” +and “Common Ethernet Support” +to your configuration. Their package names +are CYGPKG_NET, CYGPKG_NET_OPENBSD_STACK and CYGPKG_NET_ETH_DRIVERS +respectively.
A short-cut way to do this is by +using the “net” template +if it is available for your platform.
The platform-specific ethernet device driver for your platform +will be added as part of the target selection (in the +Build->Templates “Hardware” item), +along with the +PCI I/O subsystem (if relevent) and the appropriate serial device driver.
For example, the PowerPC MBX target selection adds the package +PKG_NET_QUICC_ETH_DRIVERS, +and the Cirrus Logic EDB7xxx target selection adds the package +CYGPKG_NET_EDB7XXX_ETH_DRIVERS. +After this, eCos and its tests can be built exactly as usual.
Note: By default, most of the network tests are not built. This +is because some of them require manual intervention, i.e. they are +to be run “by hand”, and are not suitable for +automated testing. To build the full set of network tests, set +the configuration option CYGPKG_NET_BUILD_TESTS “Build +networking tests (demo programs)” within “Networking +support build options”.
