I haven't used the niche stack in a long while but I think it will need to be modified in several places to support jumbo frames. To begin with the MBUFs used to store the packet data can have two different sizes, and the biggest one is just big enough for a standard frame. You'll either need to increase the MBUF size for the big packets, or somehow manage to use chains of MBUFs to store the data. There are probably several places in the code where the packet size is checked too, so you'll have to go in the source and modify it yourself.
