Redundant schechuler doesn't duplicate all packet on each subflow.

[ken32293355]

Hello,

I am using the MPTCP v0.94.8.

My setting:
kernel.osrelease = 4.14.271.mptcp
net.mptcp.mptcp_checksum = 1
net.mptcp.mptcp_debug = 0
net.mptcp.mptcp_enabled = 2
net.mptcp.mptcp_path_manager = fullmesh
net.mptcp.mptcp_scheduler = redundant
net.mptcp.mptcp_syn_retries = 3
net.mptcp.mptcp_version = 0

And I wrote a simple socket program and set this in my C program,

int enable = 1;
setsockopt(server_fd, SOL_TCP, 42, &enable, sizeof(int));
char scheduler[] = "redundant";
setsockopt(server_fd, SOL_TCP, 43, scheduler, sizeof(scheduler));

I find that the MPTCP only duplicate the packet at the begin time. No matter my throughput is, most of my packets are not duplicated.

Hi,

Thank you for the bug report.

May you please check if you can reproduce this issue with MPTCP v0.95 + the modification suggested there: #474 ?
