[RFC] Patch to improve TSO limitation formula in general

2014-09-05 Thread Hans Petter Selasky
Hi, I've tested the attached patch with success and would like to have some feedback from other FreeBSD network developers. The problem is that the current TSO limitation only limits the number of bytes that can be transferred in a TSO packet and not the number of mbuf's. The current

Hi, But is the airflow in the unit sufficient? I had this problem at a previous job - the box was running fine, the room was very cold, but the internal fans in the server were set to be very quiet. It wasn't enough to keep the ixgbe NICs happy. I had to change the fan settings to just always

There are some concerns if we use this with devices that ixl supports: - The maximum fragment size is 16KB-1, which isn't a power of 2. - You can't get the maximum TSO size for ixl devices by multiplying the maximum number of fragments by the maximum size. Instead the number of fragments is

How can sshuttle be used properly with FreeBSD (and with DNS) ?

I would like to use sshuttle (http://github.com/apenwarr/sshuttle) on FreeBSD. I have it working for TCP connections, but it does not properly tunnel DNS requests. The documentation for sshuttle says that ipfw forward rules will not properly forward UDP packets, and so when it runs on

Hello, For many years I would build FreeBSD firewalls and they would be very, very simple - I just set gateway_enable=yes in rc.conf and everything just worked. However, these firewalls *always* had real, routable IPs no both sides. Both interfaces had real, routable IPs. Now I have a
