** Changed in: linux (Ubuntu Focal)
Status: Confirmed => Fix Committed
** Description changed:
Issue found on B-5.4.0-128-generic #144~18.04.1-Ubuntu
This is a new test case from bug 1988809
Test failed with:
Running 'make run_tests -C net TEST_PROGS=fib_nexthop_nongw.sh

+
+ [Impact]
+
+ When running kselftests on Bionic with a 5.4 kernel, it would
+ fail because of no nexthop capability.
+
+ [Fix]
+
+ We query the ip command help to know whether it is implemented
+ or not, and we skip or execute the test accordingly
+
+ [Test Plan]
+
+ Running the test script directly in Bionic will throw a Skip,
+ while running it in Focal will throw the test result.
+
+ [Where problems could ocurr]
+
+ The regression potential for this is low.

+ [Other Info]
