From a2c51efe3669f0380042b2375eae79e403d3680c Mon Sep 17 00:00:00 2001 From: Ian Gudger Date: Tue, 29 Oct 2019 16:13:43 -0700 Subject: Add endpoint tracking to the stack. In the future this will replace DanglingEndpoints. DanglingEndpoints must be kept for now due to issues with save/restore. This is arguably a cleaner design and allows the stack to know which transport endpoints might still be using its link endpoints.
