Tonghao Zhang 27cb3de7f4 net: add net cookie for net device trace events
In a multi-network card or container environment, this is needed in order
to differentiate between trace events relating to net devices that exist
in different network namespaces and share the same name.

for xmit_timeout trace events:
[002] ..s1.  1838.311662: net_dev_xmit_timeout: dev=eth0 driver=virtio_net queue=10 net_cookie=3
[007] ..s1.  1839.335650: net_dev_xmit_timeout: dev=eth0 driver=virtio_net queue=10 net_cookie=4100
[007] ..s1.  1844.455659: net_dev_xmit_timeout: dev=eth0 driver=virtio_net queue=10 net_cookie=3
[002] ..s1.  1850.087647: net_dev_xmit_timeout: dev=eth0 driver=virtio_net queue=10 net_cookie=3
