Subject: [RFC PATCH net-next v3 01/21] netlink: introduce nla_put_bitfield32()
Date: Mon, 18 Feb 2019 19:21:29 +0100 (CET) [thread overview]
Message-ID: <b874a527531020f62a25391334e83c3c78ea2a90.1550513384.git.mkubecek@suse.cz> (raw)
In-Reply-To: <cover.1550513384.git.mkubecek@suse.cz>
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().
