Subject: [PATCH] net treewide: Use skb_is_gso
Date: Wed, 21 Oct 2020 18:30:30 +0800	[thread overview]
Message-ID: <20201021103030.3432231-1-yili@winhong.com> (raw)

This patch introduces the use of the inline func skb_is_gso in place of
tests for skb_shinfo(skb)->gso_size.

- if (skb_shinfo(skb)->gso_size)
+ if (skb_is_gso(skb))

- if (unlikely(skb_shinfo(skb)->gso_size))
+ if (unlikely(skb_is_gso(skb)))

- if (!skb_shinfo(skb)->gso_size)
+ if (!skb_is_gso(skb))
