In the XAUI and RXAUI Virtex-6 FPGA example design <core_name>_block.v/vhd file TXDIFFCTRL is tied to "0000" by default.
If the default of "0000" is used, it might be possible to see an Electrical Idle type condition at the other end of the link.
TXDIFFCTRL might still need to be adjusted for a particular setup, but a better default value is "1010".
