In any configuration that requires the ALTGX_RECONFIG megafunction, you must
instantiate it in your design and connect it to the 10-Gbps Ethernet IP core as shown in

On/Off
If you select a Stratix II GX device and implement the MAC + XAUI variant, you
can turn on Use external reconfig block, you can modify the properties of the
transceiver using the ALTGX_RECONFIG megafunction.
If you select a Stratix IV GX or Arria II GX device with any variant that includes
XAUI, you must include the ALTGX_RECONFIG megafunction in your design;
this option is always turned on.
For Arria GX devices, this option is not available.

describes the MAC options.
When you turn this option On, the IP core instantiates an management data
I/O (MDIO) master. The MDIO interface provides an Avalon
Memory-Mapped (Avalon-MM) to MDIO bridge to control an external PHY.
The clock divider provides the division ratio for sysclk to generate the
preferred MDIO clock (MDC). The division factor must be defined such that
the MDC frequency does not exceed 2.5 MHz.
When you turn this option On, the IP core includes registers to report
statistics on frames transmitted and received.
