Subject: [PATCH v3] cxgb4: add missing release on skb in uld_send()
Date:   Wed, 22 Jul 2020 21:58:39 -0500
Message-Id: <20200723025841.22535-1-navid.emamdoost@gmail.com>
In-Reply-To: <20200722.181436.414462601873878102.davem@davemloft.net>
References: <20200722.181436.414462601873878102.davem@davemloft.net>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

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