Linux kernel:2.6.20.21 (timesys)
I have Intel IXP435 demo board.I tested GbPCI to GbPCI throughput and GbPCI to IXP435 MII lan.but the kernel show up some error message. I try limit all network buffer 64MB, performance not bad.but, still show up error message. this message look like DMA and IRQ error. so, any comment?
Thanks
