Patch #2 adds a test case that triggers the problem. In net-next we can: 1. Add DEBUG_NET_WARN_ON_ONCE() when a port multicast context is de-initialized while enabled. 2. When de-initializing a port multicast context, synchronously shutdown all the timers that were initialized when the context was initialized. ==================== Link: https://patch.msgid.link/20260517121122.188333-1-idosch@nvidia.com Signed-off-by: Jakub Kicinski --- 90fc1a393736063b2b4077115e215a2e2eebb797
