Subject: net/bnxt: use new API to get IOVA address
X-Git-Tag: spdx-start~363
X-Git-Url: http://git.droids-corp.org/?p=dpdk.git;a=commitdiff_plain;h=42b883535804d69ca8b21b39087fc1d14a1ee3f3

net/bnxt: use new API to get IOVA address

Replace internal functions to get DMA address them with their generic
IOVA version. Also rename the 'data' variable to 'mbuf' for more
readability.
