I am working with the board [zynq ultrascale+ mpsoc zcu102]. With the 10g/25G Ethernet Subsystem IP, we have achieved the 10G speed. Now we are going forward to 25G speed.
My question is How to set GT lane in the 10g/25G Ethernet Subsystem for 25g speed. What are the things to be done from 10G to 25G ? Whether any specific part number i need to choose for 25G ? Please let me know the process to achieve 25g speed.

The ZCU102 board is populated with the Zynq UltraScale+ XCZU9EG-2FFVB1156E MPSoC which combines a powerful processing system (PS) and user-programmable logic (PL) into the same device,which has the GTH and PS-GTR, where the GTH is supports the line rate not more than 16.3Gb/s(UltraScale GTH (16.3 Gb/s): Low power & high performance for the toughest backplanes). where as the PS-GTR is support line rate upto 6.0Gb/s(UltraScale+ GTR (6.0 Gb/s): Easiest integration of common protocols to the Zynq Processor Subsystem).
since the line rate support of GTH is only till 16Gb/s so we cannot use the GTH for line rate of 25Gbpbs.
I assume and believe I have cleared your query . let me know your inputs

Then how can i achieve the line rate of 25Gbpbs ?? Please clear me.

I am passing 60 packets of data (CPRI concept) with header into 10G/25G Ethernet Subsytem.

if the GTH cannot support I think you cannot use it .

I am using the following part number : xczu19eg-ffvd1760-3-e (active). We got license key for 25G Ethernet IP.
Please see the following screenshot.
1. Pin assignments for xczu19eg-ffvd1760-3-e board.
I have set the Pins. But i am not sure whether it is right or wrong.
2. Whether lane selection is right or wrong ?

your initial query was it respect to zcu102 board right , but if your using the GTY then is supported .
for lane selection see the below image
