Subject: [PATCH net-next 0/4] libnl: enhance API to ease 64bit alignment for attribute
Date: Wed, 20 Apr 2016 10:57:31 +0200	[thread overview]
Message-ID: <1461142655-5067-1-git-send-email-nicolas.dichtel@6wind.com> (raw)
In-Reply-To: <20160419.195009.1052027353987244150.davem@davemloft.net>


Here is a proposal to add more helpers in the libnetlink to manage 64-bit
alignment issues.
Note that this series was only tested on x86.

The first patch is a fix (bug seen by code review only unless I've missed
something).
The second patch adds helpers and uses it for IFLA_STATS64.
The last two patches use the new API to align mcast stats.

We could also add helpers for nla_put_u64() and its variants.
