The existing net/netif_rx and net/netif_receive_skb trace events provide little information about the skb, nor do they indicate how it entered the stack. Add trace events at entry of each of the exported functions, including most fields that are likely to be interesting for debugging driver datapath behaviour. Split netif_rx() and netif_receive_skb() so that internal calls are not traced. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net> |
