MTU in Zynq

Hello,

 

I am trying to set the MTU in my ZC706 using ioctl, but I have an upper bound of 1500. If I try bigger, I get an error. 

 

Is it a hardware limitation?

 

Thanks,

 

Michele

I found a better framing for the question: are Jumbo frames supported?

 

Thanks,

 

Michele

But if you really do need jumbo frames, you could try to instantiate a Gigabit Ethernet Controller in the FPGA and use that instead.
