[dpdk-stable] [PATCH 18.11 03/19] net/bnxt: fix check of address mapping

[Somnath Kotur]

From: Kalesh AP <kalesh-anakkur.purayil at broadcom.com>

rte_mem_virt2iova() function returns RTE_BAD_IOVA on failure, not zero.
Fixed wrong checks in bnxt_ethdev.c.

Fixes: 62196f4e0941 ("mem: rename address mapping function to IOVA")
