This patch extends hairpin-mode command line option of test-pmd
application with an ability to configure whether Rx/Tx hairpin queue
should use locked device memory or RTE memory.
For purposes of this configurations the following bits of 32 bit
hairpin-mode are reserved:
- Bit 8 - If set, then force_memory flag will be set for hairpin RX
queue.
- Bit 9 - If set, then force_memory flag will be set for hairpin TX
queue.
- Bits 12-15 - Memory options for hairpin Rx queue:
- Bit 12 - If set, then use_locked_device_memory will be set.
- Bit 13 - If set, then use_rte_memory will be set.
- Bit 14 - Reserved for future use.
- Bit 15 - Reserved for future use.
- Bits 16-19 - Memory options for hairpin Tx queue:
- Bit 16 - If set, then use_locked_device_memory will be set.
- Bit 17 - If set, then use_rte_memory will be set.
- Bit 18 - Reserved for future use.
- Bit 19 - Reserved for future use.
