Note:
- MCDMA H-Tile design example supports SR-IOV with only 1 PF and its VFs for simulation in these configurations.
- Kernel mode driver doesn’t support SR-IOV.
- Netdev driver supports 4 PFs and 1 channel per PF.
- Packet Generate/Check and Device-side Packet loopback design example variants for BAM + MCDMA user mode of Avalon-ST interface type is temporary disabled
