Hi!
I've recently installed OpenBSD 5.0/i386 on a
virtualized root-server (Linux-KVM, dmesg below).
Installation was fine.
Now I'm dropped from multiuser to the shell,
usually a couple of seconds after login
with the message:

Hi list!
Simple(?) question:
How do I enable tcp fast retransmissions?
I've got a wireless network with a lot of interference
which results in about 30% packet loss. Fast retransmission
should help here, right?
However:
* Counter for fast retrans in 'netstat -s' is always zero.
* Nothing

Is it possible to clear the ECN bit in outgoing packings using pf?
Something like a no-ecn option, similar to scrub's no-df option.

In the stable OpenBSD 3.9 sources the maximum is _hardcoded_ to 20dBm.
