Subject: [PATCH AUTOSEL 4.14 09/10] cxgb4: add missing release on skb in uld_send()
Date: Mon, 27 Jul 2020 19:24:57 -0400	[thread overview]
Message-ID: <20200727232458.718131-9-sashal@kernel.org> (raw)
In-Reply-To: <20200727232458.718131-1-sashal@kernel.org>

From: Navid Emamdoost <navid.emamdoost@gmail.com>

[ Upstream commit e6827d1abdc9b061a57d7b7d3019c4e99fabea2f ]

In the implementation of uld_send(), the skb is consumed on all
execution paths except one. Release skb when returning NET_XMIT_DROP.
