netdev: Add tracepoints to netdev layer
This patch adds tracepoint to dev_queue_xmit, dev_hard_start_xmit, netif_rx and netif_receive_skb. These tracepoints help you to monitor network driver's input/output. <idle>-0 [001] 112447.902030: netif_rx: dev=eth1 skbaddr=f3ef0900 len=84 <idle>-0 [001] 112447.902039: netif_receive_skb: dev=eth1 skbaddr=f3ef0900 len=84 sshd-6828 [000] 112447.903257: net_dev_queue: dev=eth4 skbaddr=f3fca538 len=226 sshd-6828 [000] 112447.903260: net_dev_xmit: dev=eth4 skbaddr=f3fca538 len=226 rc=0 Signed-off-by: Koki Sanagi <sanagi.koki@jp.fujitsu.com> Acked-by: David S.
