Subject: net/bnxt: fix incorrect IO address handling in Tx
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=90362583e21407272d85882b4ff01fd2ca3f0ac7;p=dpdk.git

net/bnxt: fix incorrect IO address handling in Tx

rte_mbuf_data_iova returns a 64-bit address. But we are incorrectly
using only 32-bits of that. Use rte_cpu_to_le_64 instead of
rte_cpu_to_le_32

Fixes: 6eb3cc2294fd ("net/bnxt: add initial Tx code")
