| -max-num-devices | int | maximum number of QAT devices to be provided to the QuickAssist device plugin (default: `32`) |
| -mode | string | plugin mode which can be either `dpdk` or `kernel` (default: `dpdk`) |
| -allocation-policy | string | 2 possible values: balanced and packed. Balanced mode spreads allocated QAT VF resources balanced among QAT PF devices, and packed mode packs one QAT PF device full of QAT VF resources before allocating resources from the next QAT PF. (There is no default.) |
