Plesae find the v7 AccECN case handling patch series, which covers several excpetional case handling of Accurate ECN spec (RFC9768), adds new identifiers to be used by CC modules, adds ecn_delta into rate_sample, and keeps the ACE counter for computation, etc.
This patch series is part of the full AccECN patch series, which is available at https://github.com/L4STeam/linux-net-next/commits/upstream_l4steam/
Hi Chia-Yu,
My understanding is that you still have a set of packetdrill tests you have been using to test this AccECN patch series. For the Linux networking stack, the recent best practice for a significant patch series like this is to add packetdrill tests to the tools/testing/selftests/net/packetdrill/ directory as a separate commit in the patch series.
For a recent example, see:
selftest: packetdrill: Add max RTO test for SYN+ACK. https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next.git/commit/?...
When you next post the AccECN patch series for review, can you please include a patch at the end of the series that posts your packetdrill tests in the tools/testing/selftests/net/packetdrill/ directory? In the commit description for that patch, please include a mention of the packetdrill SHA1 you are using and a link to the packetdrill branch you are using, somewhere on github or similar. Then I will look into merging any packetdrill tool changes that you are depending on, if there are packetdrill commits that you depend on that I have not merged into packetdrill yet.
Thanks! neal
