Subject: [PATCH net-dev] net: Exposing more skb fields in netif_receive_skb trace event
Date: Wed, 9 Jun 2021 17:36:54 +0800	[thread overview]
Message-ID: <20210609093656.8984-1-edwardwu@realtek.com> (raw)

This exposing helps to analyze network behavior.

In performance tuning, we will check nr_frags to analyze
GRO aggregation behavior. By this commit, we can
enable netif_receive_skb trace event for dynamic debugging.
