Subject: [PATCH iproute2-next v1 17/19] rdma: Unify netlink attribute checks prior to prints
Date: Wed, 20 Feb 2019 09:21:34 +0200 [thread overview]
Message-ID: <20190220072136.3840-18-leon@kernel.org> (raw)
In-Reply-To: <20190220072136.3840-1-leon@kernel.org>
From: Leon Romanovsky <leonro@mellanox.com>
Place check if netlink attribute available in general place,
instead of doing the same check in many paces.
