Difference between netdev_rx_handler_register() and dev_add_pack()
Hi,
Can any one explain what is the difference between netdev_rx_handler_register() and dev_add_pack() as both of these two APIs are used to register the handler to handle the received packets??
where and in which context I should used which one??
iirc netdev_rx_handler_register is registering to handle incoming packets on a specific network device and dev_add_pack() puts the handler in the chain of handlers for the passed in protocol type.
So if you wanted to look at all the incoming on say eth0 then use netdev_rx_handler_register, if you are looking for say udp packets and you don't care what device it's coming from use dev_add_pack
