Message-Id: <1492361304-6116-1-git-send-email-dsa@cumulusnetworks.com>
Date: Sun, 16 Apr 2017 09:48:24 -0700
From: David Ahern <dsa@...ulusnetworks.com>
To: netdev@...r.kernel.org
Cc: jhs@...atatu.com, David Ahern <dsa@...ulusnetworks.com>
Subject: [PATCH net-next] net: rtnetlink: plumb extended ack to doit function
Add netlink_ext_ack arg to rtnl_doit_func. Pass extack arg to nlmsg_parse
for doit functions that call it directly.
This is the first step to using extended error reporting in rtnetlink.
>From here individual subsystems can be updated to set netlink_ext_ack as
needed.
