Hi, Iain
Can you please check whether the OFED has been installed with '--upstream-libs --dpdk' options? I mean,
./mlnxofedinstall --upstream-libs --dpdk
It is documented in "21.7. Quick Start Guide on OFED".
Since 17.11, we started to support upstream libraries (rdma-core in linux community).
Thanks,
Yongseok
