Definition at line 66 of file rte_pmd_dpaa2_qdma.h.

uint16_t max_vqs

Maximum number of VQ's to be used.

Definition at line 68 of file rte_pmd_dpaa2_qdma.h.

uint8_t mode

mode of operation - physical(h/w) or virtual

Definition at line 70 of file rte_pmd_dpaa2_qdma.h.

uint8_t format

FD format

Definition at line 72 of file rte_pmd_dpaa2_qdma.h.

int fle_pool_count

User provides this as input to the driver as a size of the FLE pool. FLE's (and corresponding source/destination descriptors) are allocated by the driver at enqueue time to store src/dest and other data and are freed at the dequeue time. This determines the maximum number of inflight jobs on the QDMA device. This should be power of 2.
