Hi Adam, Thanks for the updates.
I have one issue with casperfpga tools. After I changed the golden and boot images as well as Spartan fpga firmware (from https://github.com/ska-sa/skarab_bsp_images) to support CASPER toolflow (https://github.com/ska-sa/mlib_devel), I am able to compile and program the SKARAB using casperfpga with 1GbE port but connection via 40GbE needs reprogramming of the fpga. It also often complains about the MTU to be set to 9000 even though it is already set on our switch as well as linux machine. Does the 40G core MTU needs to be manually set as well ?
