Subject: [PATCH iproute2-next v2 17/19] rdma: Unify netlink attribute checks prior to prints
Date: Sat, 23 Feb 2019 11:15:26 +0200	[thread overview]
Message-ID: <20190223091528.8509-18-leon@kernel.org> (raw)
In-Reply-To: <20190223091528.8509-1-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.
