This reverts commit 493bc90a96839ffde5e6216c62c025d2f9e6efc3.
This commit was introduced because of some testing capabilities
involving ack handling. Not we want to collect errors so let's first
revert this commit, then right after reintroduce the Tx trac handling
which is the only one that makes sense for now.
