I meant the rx_err signal on the avalon bus. It is a 6-bit wide vector that indicates various problems detected when receiving the frame.

For the CRC check it is in fact enabled in the configuration registers, not in the megawizard, sorry.

Now from the packet that isn't received by the PC there can be multiple reasons. Does the LED on the PC network port blink? If possible, try to disable any hardware acceleretion from the PC's network drivers. Some chipsets automatically discard mal formed packets, or packets with wrong CRC.

How is the tx_err signal cabled to your PHY chip?
