[dpdk-stable] patch 'mbuf: explicit cast of headroom on reset' has been queued to LTS release 17.11.5

[Yongseok Koh <yskoh@mellanox.com>]

Hi,

FYI, your patch has been queued to LTS release 17.11.5

Note it hasn't been pushed to http://dpdk.org/browse/dpdk-stable yet.
It will be pushed if I get no objections before 01/04/19. So please
shout if anyone has objections.

Also note that after the patch there's a diff of the upstream commit vs the patch applied
to the branch. If the code is different (ie: not only metadata diffs), due for example to
a change in context or macro names, please double check it.

Thanks.

Yongseok

Subject: [PATCH] mbuf: explicit cast of headroom on reset

[ upstream commit 553ff494cb4d7fa9539911d3bbb4d94de5f69f20 ]

GCC 8.1 warned:

rte_common.h:384:2:
warning: conversion from 'int' to 'uint16_t'
{aka 'short unsigned int'} may change value [-Wconversion]
  __extension__ ({ \
  ^~~~~~~~~~~~~
rte_mbuf.h:1204:16:
note: in expansion of macro 'RTE_MIN'
  m->data_off = RTE_MIN(RTE_PKTMBUF_HEADROOM, (uint16_t)m->buf_len);

RTE_PKTMBUF_HEADROOM is typ 128, so it doesn't make trouble.

Fixes: 08b563ffb19d ("mbuf: replace data pointer by an offset")
