Hi Geliang, Thank you for your modifications, that's great! But sadly, our CI spotted some issues with it when trying to build it. You can find more details there: https://patchwork.kernel.org/project/mptcp/patch/bdcd868980996e3b9ca84b361ab5f561cbc2d0af.1667889809.git.geliang.tang@suse.com/ https://github.com/multipath-tcp/mptcp_net-next/actions/runs/3417050364 Status: failure Initiator: MPTCPimporter Commits: https://github.com/multipath-tcp/mptcp_net-next/commits/5906795b5bb9 Feel free to reply to this email if you cannot access logs, if you need some support to fix the error, if this doesn't seem to be caused by your modifications or if the error is a false positive one.

This patch adds the redundant BPF MPTCP scheduler test: test_red(). Use sysctl to set net.mptcp.scheduler to use this sched. Add two veth net devices to simulate the multiple addresses case. Use 'ip mptcp endpoint' command to add the new endpoint ADDR_2 to PM netlink. Send data and check bytes_sent of 'ss' output after it to make sure the data has been redundantly sent on both net devices.
