| I'm still trying to follow a packet (or even better an sk_buff) from the
| NIC card to user space. I think I have a good chunk of it figured out,
| but I'm missing a bit from the time that the __netif_rx_schedule()
| routine calls __cpu_raise_softirq() until the routine net_rx_action()
| occurs. I read in a book on Linux TCP/IP implementation that the
| softirq basically leads to a call to net_rx_action(), but I don't see
| the connection yet. It's probably due to my lack of understanding of
| IRQ's (and software IRQ's).

What are you going to do with this good info when you have it?
Something like putting it on a web page would be very good, so that
other people with similar questions can have a reference to look at.
