following up on https://github.com/Xilinx-CNS/onload/issues/64 i manage to load onload (using onload_tool reload)

dmesg

since my NIC is named ens3 , im assuming i need to run the following line to register my intel nic with onload echo ens3 > /sys/module/sfc_resource/afxdp/register“

however, /sys/module/sfc_resource/afxdp/register seems to be missing..

$ ls /sys/module/sfc_resource/
coresize  holders  initsize  initstate  notes  parameters  refcnt  sections  srcversion  taint  uevent
$ ethtool -i ens3

Hi arieb,

[ 1173.277519] [onload] Onload 7.1.3.202

however, /sys/module/sfc_resource/afxdp/register seems to be missing..

Onload version 7.1 does not include AF_XDP support - you need to take a copy from this repository to get that.
