You can enable the TX bit reversal feature in Basic/Custom (Standard PCS), Basic/Custom w/ Rate Match (Standard PCS) and in Standard PCS low latency mode.

This feature is parameter-based, and creates no additional ports. If there is more than one channel in the design, all channels have TX bit reversal. To enable TX bit reversal, select the Enable TX bit reversal option in the Native PHY IP core.
