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")
