The FPGA is programmed, and indeed I'm using the second MAC routed through PL to SFP. The interesting thing is that I'm seeing the exact behavior on the other side (another Zynq7 board), with eth0 having lots of interrupts. It seems that the interface receiving packets doesn't have a high IRQ activity in contrast to the one sending packets. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
