From e42a43a5cab2e019b5ab82bedb1340854709154d Mon Sep 17 00:00:00 2001 From: "David S. Miller" Date: Mon, 6 Aug 2018 23:12:17 -0700 Subject: [PATCH] lan78xx: Do not access skb_queue_head list pointers directly. Use skb_queue_walk() instead. Adjust inner loop test to utilize and skb_queue_is_first(). Unfortunately we have to keep pkt_cnt around because it is used by a latter loop in this function. Signed-off-by: David S.
