100 GbE on a Jetson AGX Orin dev kit

What is our best chance to use a 100 GbE NIC (with DPDK) in a Jetson AGX Orin dev kit? So far, we tried:

• an NVIDIA MCX653105A-ECAT: not detected with lspci after booting (not even after echo 1 >/sys/bus/pci/rescan).


• an Intel e810: works fine with the ice driver, but not with DPDK, as the vfio_pci driver complains that IOMMU group 12 is not viable


• a QNAP QXG-25G2SF-CX6: works (also with DPDK), but needs multiple boot attempts to be detected, and is only dual 25 GbE.
  
  We use JetPack 5.0.2 with the Jetson Linux 35.1 BSP. Solutions as described in SOLUTION/TUTORIAL: Jetson ORIN Enabling PCIE power and Jetson AGX Orin board not able to enumerate FPGA PCIe card (Latest kernel 35.1.0) did not solve our problems. The dmesg output is attached. Any help is more than welcome!
