Subject: [PATCH v3 net 9/9] benet: remove skb_share_check from xmit path
Date: Tue, 11 Feb 2020 16:00:28 +0100	[thread overview]
Message-ID: <20200211150028.688073-10-Jason@zx2c4.com> (raw)
In-Reply-To: <20200211150028.688073-1-Jason@zx2c4.com>

This is an impossible condition to reach; an skb in ndo_start_xmit won't
be shared by definition.
