[dpdk-stable] patch 'net: explicit cast of protocol in IPv6 checksum' 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] net: explicit cast of protocol in IPv6 checksum

[ upstream commit 8bf255bb3862d8f35496b26bc8c2511239bdc18b ]

GCC 8.1 warned:

In function 'rte_ipv6_phdr_cksum':
rte_ip.h:378:18: warning: conversion to 'uint32_t' {aka 'unsigned int'}
from 'int' may change the sign of the result [-Wsign-conversion]
  psd_hdr.proto = (ipv6_hdr->proto << 24);

Fixes: 6006818cfb26 ("net: new checksum functions")
