I am trying to use both the devices provided in OpenNIC shell with DPDK. However setting the registers as mentioned in the docs, only the first device is used and the other doesn't get initialized. Logs from EAL: `EAL: Detected 128 lcore(s) EAL: Detected 2 NUMA nodes EAL: Multi-process socket /var/run/dpdk/rte/mp_socket EAL: Selected IOVA mode 'VA' EAL: 2048 hugepages of size 2097152 reserved, but no mounted hugetlbfs found for that size EAL: Probing VFIO support...

First device is initialized properly

Second device(17:00.1) initialization fails
I hwas following the README here https://github.com/Xilinx/open-nic-dpdk to initialize my own dpdk app, instead of Pktgen. Set all registers as mentioned but only first PF works and the other one doesn't.
