skbuff: increase verbosity when dumping skb data
skb_warn_bad_offload and netdev_rx_csum_fault trigger on hard to debug issues. Dump more state and the header. Optionally dump the entire packet and linear segment. This is required to debug checksum bugs that may include bytes past skb_tail_pointer(). Both call sites call this function inside a net_ratelimit() block. Limit full packet log further to a hard limit of can_dump_full (5). Based on an earlier patch by Cong Wang, see link below. Changes v1 -> v2 - dump frag_list only on full_pkt Link: Signed-off-by: Willem de Bruijn <> Signed-off-by: David S. Miller <>
