Re: Chelsio NIC with RSS - Traffic distribution to different Queues

We are familiar with «hw.cxgbe.rsrv_noflowq», but as you already stated it’s only for TX direction, it doesn’t help us at all.

Our problem is in fact, that on FreeBSD only CPU0 seems to do the slow protocol (LACP, CARP,…) stuff and even though the other CPUs are completely idle, if CPU0 has 100% load (which is in fact possible to achieve with one iperf session) you can create a scenario where LACP/CARP stops working due to the load on CPU0. So the idea would be to get rid of the RSS load of CPU0 to ensure that the slow protocols are always working as expected.

To sum it up, yes I’m in theory able to test a RX patch, as it is only a test setup. However I’m completely new in FreeBSD and we are using it only because our firewall (OPNsense) does use it. FreeBSD came on the ISO with the installation medium. So please explain in detail what we have to do…
