From: Prashant Gupta <[email protected]> Add RTE_PROC_PRIMARY checks in device initialization paths for net/dpaa, crypto/dpaa_sec and dma/dpaa drivers. Secondary processes should skip hardware initialization to prevent segfaults when accessing hardware registers that are only mapped in the primary process.
