Any PCIe expert out there ?

I'd like to skip phase 2&3 equalization when switching to Gen3. Root is a RPi5 and device is a xilinx fpga I control ...

@tnt can I ask why out of curiosity?

@Lunaphied Trying Gen3 over optical link and obviously the feedback loop of the EQ doesn't work because changes in the TX won't directly affect the other side because of the electrical -> optical -> electrical conversion.
