Can anyone help me to understand how interrupts are handled for PCI ether card? I find ipintr() is called to handle incoming IP packets from the PCI ether card on my machine. However, when I traced in the code, I found ipintr is called from DONETISR which is invoked in arch/i386/isa/icu.c.
So my question is why functions defined in isa (supposed written for ISA cards) are used for PCI devices?
Thanks for the help!
