A lot of test cases in the file are related to the idle and unbalanced
timers of resilient nexthop groups and these tests are reported to be
flaky on slow machines running debug kernels.
Rather than marking a lot of individual tests with xfail_on_slow(),
simply mark all the tests. Note that the test is stable on non-debug
machines and that with debug kernels we are mainly interested in the
output of various sanitizers in order to determine pass / fail.

selftests: devlink_lib: Fix bouncing of netdevsim DEVLINK_DEV2021-06-08T21:39:07+00:00Petr Machatapetrm@nvidia.com2021-06-08T12:44:10+00:00urn:sha1:0521a262f043ea521790ed2976141086c75d2f74
In the commit referenced below, a check was added to devlink_lib that
asserts the existence of a devlink device referenced by $DEVLINK_DEV.
Unfortunately, several netdevsim tests point DEVLINK_DEV at a device that
does not exist at the time that devlink_lib is sourced. Thus these tests
spuriously fail.
Fix this by introducing an override. By setting DEVLINK_DEV to an empty
string, the user declares their intention to handle DEVLINK_DEV management
on their own.
In all netdevsim tests that use devlink_lib and set DEVLINK_DEV, set
instead an empty DEVLINK_DEV just before sourcing devlink_lib, and set it
to the correct value right afterwards.
Fixes: 557c4d2f780c ("selftests: devlink_lib: add check for devlink device existence")
