O2Micro success

Hello! I just wanted you to tell that I got the pccard slot in my IPC Highnote S15 to work with 4.8-Release. (There was a similar question a week ago). The chipset is an O2Micro OZ 6812 and is recognized as: pcic0: <O2micro 6812/6872 PCI-Cardbus Bridge> irq 11 at device 3.0 on pci0 pcic0: PCI Memory allocated: 0x88000000 pcic0: Polling mode pcic0: Warning: O2micro OZ68xx chips may not work pccard0: <PC Card 16-bit bus (classic)> on pcic0 The trick was to set hw.pcic.intr_path="1" in /boot/loader.conf. The cards works in polled mode (hw.pcic.irq="0"). Setting an irq has no positive effect. The performance is very bad. With a 3COM 574 card which only gets about 10 MBit/s (according to netperf) on a 100 MBit/s direct connection to another 3COM 905, and CPU is nearly on 100%. The built-in LAN (sis) gets 95 MBit/s with very low CPU usage, so I guess it is the polling mode. The biggest advantage is that I can use my COM1 modem card now, because the built-in PCTel modem will probably nerver come to work.
