From 7fe50ac83f4319c18ed7c634d85cad16bd0bf509 Mon Sep 17 00:00:00 2001 From: Cong Wang Date: Mon, 12 Nov 2018 14:47:18 -0800 Subject: net: dump more useful information in netdev_rx_csum_fault() Currently netdev_rx_csum_fault() only shows a device name, we need more information about the skb for debugging csum failures. Sample output: ens3: hw csum failure dev features: 0x0000000000014b89 skb len=84 data_len=0 pkt_type=0 gso_size=0 gso_type=0 nr_frags=0 ip_summed=0 csum=0 csum_complete_sw=0 csum_valid=0 csum_level=0 Note, I use pr_err() just to be consistent with the existing one.
