I have been running the system for 4 days now with this driver. My application has not stopped accepting connections, irq rate is low, and there are no rx/tx errors reported. Everything looks good. - Patched driver. Your initial import plus the IRQ fix still shows rx errors, and my application had stopped accepting connections. I have not tried the patch in your last email, and im not sure when i will be able to to as these systems are in production. Perhaps someone else could test it? As soon as i get a chance i will let you know how it goes. Thanks for the work on this.
