Use the latter from router_mpath_nh.sh and router_mpath_nh_res.sh. The test works by sending traffic through a NH group, and checking that the reported values correspond to what the link that ultimately receives the traffic reports having seen.

selftests: forwarding: Remove duplicated lib.sh content 2024-01-31T10:55:11+00:00 Petr Machata petrm@nvidia.com 2024-01-26T23:21:23+00:00 521ed1ce94bb35842357fb71918d8ebed552f941 commit 25ae948b4478 ("selftests/net: add lib.sh") added net/lib.sh to contain code shared by tests under net/ and net/forwarding/. However, this caused issues with selftests from directories other than net/forwarding/, in particular those under drivers/net/. Those issues were avoided in a simple way by duplicating some content in commit 2114e83381d3 ("selftests: forwarding: Avoid failures to source net/lib.sh"). In order to remove the duplicated content, restore the inclusion of net/lib.sh from net/forwarding/lib.sh but with the following changes: * net/lib.sh is imported through the net_forwarding_dir path The original expression "source ../lib.sh" would look for lib.sh in the directory above the script file's one, which did not work for tests under drivers/net/. * net/lib.sh is added to TEST_INCLUDES Since net/forwarding/lib.sh now sources net/lib.sh, both of those files must be exported along with tests which source net/forwarding/lib.sh.

contain code shared by tests under net/ and net/forwarding/. However, this
caused issues with selftests from directories other than net/forwarding/,

In order to remove the duplicated content, restore the inclusion of
net/lib.sh from net/forwarding/lib.sh but with the following changes:

* net/lib.sh is imported through the net_forwarding_dir path
The original expression "source ../lib.sh" would look for lib.sh in the
directory above the script file's one, which did not work for tests under
drivers/net/.

* net/lib.sh is added to TEST_INCLUDES
Since net/forwarding/lib.sh now sources net/lib.sh, both of those files
must be exported along with tests which source net/forwarding/lib.sh.
