I am trying to enable jumbo frames transmission and reception on NXP S32G Evaluation board, however, the MTU size is not
 changing above 1500. The following steps are done in dwcqeos.c to enable Jumbo Frames:

1) Enabled JE (Jumbo Frames Enable) and GPSLCE ( Giant Packet Size Limit Control Enable)
2) Disabled Store & Forward Mechanism (RSF, TSF)
3) MTU reconfigured from ETHERMTU to ETHERMTU_JUMBO
4) Media reconfigured from NIC_MEDIA_802_3 to NIC_MEDIA_CUSTOM

I have also tried executing the steps mentioned in the below link to change MTU manually, however, it is giving an error
 stating " SIOCSIFMTU: Invalid argument" for values above 1500:

Any help would be greatly appreciated. Thank you in advance for you support!
