Tcd he files using rte_malloc are not the ones including rte_malloc.h

$ git grep rte_malloc
enetc4_ethdev.c:        txr->q_swbd = rte_malloc(NULL, size, ENETC_BD_RING_ALIGN);
enetc4_ethdev.c:        rxr->q_swbd = rte_malloc(NULL, size, ENETC_BD_RING_ALIGN);
enetc4_ethdev.c:                rss_table = rte_malloc(NULL, hw->num_rss * sizeof(*rss_table), ENETC_CBDR_ALIGN);
enetc_cbdr.c:   tmp = rte_malloc(NULL, data_size, ENETC_CBDR_ALIGN);
enetc_cbdr.c:   cbdr->addr_base = rte_malloc(NULL, size, ENETC_CBDR_ALIGN);
enetc_ethdev.c: txr->q_swbd = rte_malloc(NULL, size, ENETC_BD_RING_ALIGN);
enetc_ethdev.c: txr->bd_base = rte_malloc(NULL, size, ENETC_BD_RING_ALIGN);
enetc_ethdev.c: rxr->q_swbd = rte_malloc(NULL, size, ENETC_BD_RING_ALIGN);
enetc_ethdev.c: rxr->bd_base = rte_malloc(NULL, size, ENETC_BD_RING_ALIGN);
enetc_rxtx.c:#include "rte_malloc.h"

The took iwyu gives hint as to recommended includes. Don't trust it blindly
but for example:
$ iwyu -I drivers/bus/pci -I drivers/common/dpaax -I lib/ethdev -I lib/net -I lib/eal/include -I drivers/bus/vdev -I lib/kvargs drivers/net/enetc/enetc_ethdev.c 

drivers/net/enetc/enetc_ethdev.c should add these lines:

drivers/net/enetc/enetc_ethdev.c should remove these lines:
