When receiving a packet, after the NET_RX_SOFTIRQ posted the skb to
softnet_data, what happened? In case of IPv4, I think the skb should
travel all the way up to a struct sock, then waiting there for a
syscall, right?
But I can't track the path down. I can't make the path in the
syscall context connected to the interrupt context. Someone please
help me understand this! Thank you very much!
Yours,
zw
