"QuoteI have read a lot on the previous issues that have popped up with this controller since it was baked into FreeBSD and I have been researching kernel tunables to try and increase throughput. I have noticed in my pursuit that it seems like opnsense is not loading the igc driver. When I run kldstat, I am not seeing a module loaded for the card but somehow the card is still identified:
When I run 'pciconf -a igc0', it only shows that it is attached and no driver information. Am I missing something here? I know that the freebsd man page for IGC4 says that the driver was not implemented until 14.0, but how is this card working under freebsd 13.2 base? The reason I am asking about this is that I found a driver pack that references the I225-V card that was updated on 12/23/2023 here (https://www.intel.com/content/www/us/en/download/15084/intel-ethernet-adapter-complete-driver-pack.html) and was wondering if maybe this could be helpful to alleviate the rampant issues with this controller. Other reason that I am curious is because I found this paper "Tuning FreeBSD for routing and firewalling" (https://papers.freebsd.org/2018/asiabsdcon/cochard-tuning_freebsd_for_routing_and_firewalling.files/cochard-tuning_freebsd_for_routing_and_firewalling-paper.pdf referenced in another post under this forum and it makes mention of setting the receive process limit to unlimited on Intel controllers; however, 'sysctl -a | grep rx_process_limit' only returns an oid of "hw.vtnet.rx_process_limit: 1024".
Am I missing something on this whole thing?
I'm having this exact issue. Did you ever find a fix to this?
