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.
