sefltests: netdevsim: wait for devlink instance after netns removal When devlink instance is put into network namespace and that network namespace gets deleted, devlink instance is moved back into init_ns. This is done as a part of cleanup_net() routine. Since cleanup_net() is called asynchronously from workqueue, there is no guarantee that the devlink instance move is done after "ip netns del" returns. So fix this race by making sure that the devlink instance is present before any other operation.

selftests: netdevsim: Increase sleep time in hw_stats_l3.sh test hw_stats_l3.sh test is failing often for l3 stats shows less than 20 packets after 2 seconds sleep. This is happening since there is a race between the 2 seconds sleep and the netdevsim actually delivering the packets. Increase the sleep time so the packets will be delivered successfully on time.

selftests: devlink_lib: Fix bouncing of netdevsim DEVLINK_DEV 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.

selftests: netdevsim: set test timeout to 10 minutes commit afbf75e8da8ce8a0698212953d350697bb4355a6 upstream. The longest running netdevsim test, nexthop.sh, currently takes 5 min to finish. Around 260s to be exact, and 310s on a debug kernel. The default timeout in selftest is 45sec, so we need an explicit config. Give ourselves some headroom and use 10min. Commit under Fixes isn't really to "blame" but prior to that netdevsim tests weren't integrated with kselftest infra so blaming the tests themselves doesn't seem right, either.
