Date: Mon, 25 Mar 2019 18:08:00 +0100 (CET) From: Michal Kubecek <mkubecek@...e.cz> To: David Miller <davem@...emloft.net>, netdev@...r.kernel.org Cc: Jakub Kicinski <jakub.kicinski@...ronome.com>, Jiri Pirko <jiri@...nulli.us>, Andrew Lunn <andrew@...n.ch>, Florian Fainelli <f.fainelli@...il.com>, John Linville <linville@...driver.com>, Stephen Hemminger <stephen@...workplumber.org>, linux-kernel@...r.kernel.org Subject: [PATCH net-next v5 02/22] netlink: introduce nla_put_bitfield32() Similar to other data types, this helper puts NLA_BITFIELD32 attribute into a netlink message. It takes separate value and selector arguments, if there is a struct nla_bitfield32 already, one can use nla_put().
