Created attachment 255776 [details] Screenshot I think I am missing something. In the old X722 there was a kernel module “iw_ixl” and a loader “hw.ixl.enable_iwarp=1”. For the E810, I can't find anything like “iw_ice”. root@FreeBSD: # root@FreeBSD: # uname -a FreeBSD hyper7 14.1-RELEASE-p5 FreeBSD 14.1-RELEASE-p5 GENERIC amd64 root@FreeBSD:" root@FreeBSD:# root@FreeBSD: #kldstat grep -e ice -e krping 6 1 0xffffffff8220f000 abd58 ice_ddp.ko 271 0xffffffff83440000 8390 krping.ko root@FreeBSD: #nohup nc -4kl 70 & root@FreeBSD:" # appending output to nohup.out root@FreeBSD:" # root@FreeBSD:" # ifconfig icel | grep inet inet 192.168.1.2 netmask 0xffffff00 broadcast 192.168.1.255 root@FreeBSD: # root@FreeBSD: # echo "verbose, server, addr=192.168.1.2, port=70" > /dev/krping krping: write string = Iverbose, server, addr=192.168.1.2, port=701 <3>krping: rdma_bind_addr error -19 root@FreeBSD: # Dec 5 14:18:24 hyper7 syslogd: last message repeated 1 times root@FreeBSD:" # cat /dev/krping root@FreeBSD:" # Could someone please provide a sample configuration for both iWARP and RoCEv2 for FreeBSD 14 using Intel E810? https://edc.intel.com/content/www/br/pt/design/products/ethernet/adapters-and-devices-user-guide/29.2.1/remote-direct-memory-access-rdma/
