Arnaldo,
Setting tx_qlen=0 did not help, the receiver receives only 1 packet, despite of sender's sending 10 packets. Attached are the dmesg output of sender & receiver. I modified the DCCP code on the sender side to print some debug messages (input/output to/from functions, etc.).
BTW, I am using CCID3.

Yes, 4, 5 packets should be, in dccp_sendmsg:
if (sysctl_dccp_tx_qlen &&
(sk->sk_write_queue.qlen >= sysctl_dccp_tx_qlen)) {
rc = -EAGAIN;
goto out_release;
}
Leandro and Burak: could you please try setting sysctl_dccp_tx_qlen to
zero? doing this:
[root@qemu ~]# cat /proc/sys/net/dccp/default/tx_qlen
5
[root@qemu ~]# echo 0 > /proc/sys/net/dccp/default/tx_qlen
[root@qemu ~]# cat /proc/sys/net/dccp/default/tx_qlen
0
[root@qemu ~]#
And report the results?
