4.19-stable review patch. If anyone has any objections, please let me know.
------------------
From: Wang Hai <wanghai38@xxxxxxxxxx>
[ Upstream commit 2cb3f56e827abb22c4168ad0c1bbbf401bb2f3b8 ]
The sun3_82586_send_packet() returns NETDEV_TX_OK without freeing skb
in case of skb->len being too long, add dev_kfree_skb() to fix it.
Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2")
