From: Amit Cohen <redacted> [ Upstream commit e67dfb8d15deb33c425d0b0ee22f2e5eef54c162 ] Several tests do not set some ports down as part of their cleanup(), resulting in IPv6 link-local addresses and associated routes not being deleted. These leaks were found using a BPF tool that monitors ASIC resources. Solve this by setting the ports down at the end of the tests.
