[ Upstream commit 2c28ee720ad14f58eb88a97ec3efe7c5c315ea5d ]
Jakub reported increased flakiness in bond_macvlan_ipvlan.sh on regular kernel, while the tests consistently pass on a debug kernel. This suggests a timing-sensitive issue.
To mitigate this, introduce a short sleep before each xvlan_over_bond connectivity check. The delay helps ensure neighbor and route cache have fully converged before verifying connectivity.
The sleep interval is kept minimal since check_connection() is invoked nearly 100 times during the test.
