You can enable the TX byte 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 byte reversal. To enable TX byte reversal, select the Enable TX byte reversal option in the Native PHY IP core.
