[dpdk-dev] [PATCH v2 39/41] net/qede: use contiguous allocation for DMA memory

Notes:
    Doing "grep -R rte_memzone_reserve drivers/net/qede" returns the following:
    
    drivers/net/qede/qede_fdir.c:     mz = rte_memzone_reserve_aligned(mz_name, 
QEDE_MAX_FDIR_PKT_LEN,
    drivers/net/qede/base/bcm_osal.c: mz = 
rte_memzone_reserve_aligned_contig(mz_name, size,
    drivers/net/qede/base/bcm_osal.c: mz = 
rte_memzone_reserve_aligned_contig(mz_name, size, socket_id, 0,
    
    I took a brief look at memzone in qede_fdir and it didn't look like memzone
    was used for DMA, so i left it alone. Corrections welcome.
