Subject: [PATCH AUTOSEL 5.15 27/41] myri10ge: fix an incorrect free for skb in myri10ge_sw_tso
Date: Mon, 11 Apr 2022 20:46:39 -0400	[thread overview]
Message-ID: <20220412004656.350101-27-sashal@kernel.org> (raw)
In-Reply-To: <20220412004656.350101-1-sashal@kernel.org>

From: Xiaomeng Tong <xiam0nd.tong@gmail.com>

[ Upstream commit b423e54ba965b4469b48e46fd16941f1e1701697 ]

All remaining skbs should be released when myri10ge_xmit fails to
transmit a packet. Fix it within another skb_list_walk_safe.
