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/076285ed7f05ec809cfb5866c6ff2d6b8cd04e95.1654065674.git.geliang.tang@suse.com/ https://github.com/multipath-tcp/mptcp_net-next/actions/runs/2419771412 Status: failure Initiator: MPTCPimporter Commits: https://github.com/multipath-tcp/mptcp_net-next/commits/f2e8aeb9dc5b 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 round-robin BPF MPTCP scheduler test. Use sysctl to set net.mptcp.scheduler to use this sched. Add a veth net device to simulate the multiple addresses case. Use 'ip mptcp endpoint' command to add this new endpoint to PM netlink. Send data and check bytes_sent of 'ss' output after it to make sure the data has been sent on the new veth net device.
