Hello, I cannot use level-triggered interrupts with GPIO on the RPi, so I cannot test this specific patch. However I agree with the idea of level-triggered interrupts, that would fix all major problems related to missed interrupts.
Beside this I'm running a ping -f since more than two hours now and it seems to work well.
