From 8a886b142bd03d36612747e9aefdf0282c8b02dd Mon Sep 17 00:00:00 2001 From: Paolo Abeni Date: Wed, 28 Jul 2021 18:24:00 +0200 Subject: sk_buff: track dst status in slow_gro Similar to the previous patch, but covering the dst field: the slow_gro flag is additionally set when a dst is attached to the skb RFC -> v1: - use the existing flag instead of adding a new one Signed-off-by: Paolo Abeni Signed-off-by: David S.
