Thanks a lot for publishing the latest patch. Already tried it on two phyiscal
machines with directly connected NICs.
Great, thanks for testing it out.
"iperf" looks nice:

TCP networking is rather unstable after some "iperf" executions. So that new
SSH connections aren't possible anymore.
Everything more complex than "iperf" - like NFS and FTP usage - leads to a
kernel panic (page fault).
Do you want any crash dumps? If yes, where do you want them to be uploaded?
Yes, that would be helpful (I'll send you a link to a drop box). If you
were able to email me the core text files that might also help.
FWIW: I haven't set up any special routings or PF rules at all:
===============================================================================
MPTCP1
------
ifconfig_em1="10.255.255.10/8 -tso"
ifconfig_em0="192.168.1.1/24 -tso"
ifconfig_em2="192.168.2.1/24 -tso"
MPTCP2
------
ifconfig_em1="10.255.255.11/8 -tso"
ifconfig_em0="192.168.1.2/24 -tso"
ifconfig_em2="192.168.2.2/24 -tso"
===============================================================================
Okay, I'll set up something similar. Did you configure any other TCP
sysctls?
cheers,
nigel
Thanks for all your work and regards,
Nils
