Chelsio Advanced Configuration
-
Thank you for the reply. Our use case is latency sensitive and any improvement, no matter how small, is time well spent. I do however understand that PfSense is mostly only forwarding packets so at the very least it would be interesting to benchmark the results after enabling these features.
These cards are quite expensive and even sold on the netgate store, that being said they are essentially being endorsed by the company as a preferred adapter. I see no reason why all the available features should not be readily accessible within PfSense by default? Is this a feature request that can be made somewhere? -
Sure you can open a feature request here:

For anyone interested, a feature request has been added to the bug tracker here: https://redmine.pfsense.org/issues/9091
More information on offloads from https://service.chelsio.com/beta/drivers/ChelsioUwire-FBSD-3.3.0.1/README.txt
" When a TOE capable interface is the outbound path to a destination to which a
new connection is being established, the connection should be offloaded
automatically. "It would stand to reason that if your system was setup to use one or more Chelsio adapters, either exclusively or as an adapter that saw heavy traffic (WAN facing adapter), then every packet PfSense routed/forwarded over one such adapter would benefit from offloading.

Checking in 15 months later to see if any new information on this is available.

Did you ever try loading the module from FreeBSD?
Did it work? Help at all?

I'm not sure how to do that exactly. Previous attempts lead me to believe that I would need to build PfSense from source to include the module.
-
What I would expect is you copy the t4_tom.ko module from a suitable FreeBSD version and kldload it. That's the first thing to try here.

Indeed, very useful information, this website is an invaluable resource.
I would be willing to test the module in my system if anyone were able to provide it.
Hope this can be added to the baseline PfSense one day..
As far as firewall/packet forwarding is concerned I don't know if it will make much of a difference but there are plenty of packages that could take advantage of this, squid, maybe pfblocker, among others and with no change to their source required. TCP/UDP offload from the CPU directly onto the Chelsio T4/T5/T6 ASIC freeing up resources for the rest of the system to do normal packet forwarding/firewalling.
The issue on redmine had been assigned to someone at one point but it was eventually unassigned for some reason...

Try these. I can't test them against hardware but they load fine in 2.5.2:
