The code says "no." <http://git.denx.de/?p=u-boot.git;a=blob;f=net/net.c;h=78128772fe5cda166ea74aa8ac95832d8d155b55;hb=HEAD#l1407> if (ip->ip_off & htons(0x1fff)) { /* Can't deal w/ fragments */ return; That's too bad, bigger packets can help substantially with throughput on TFTP (throughput is hammered by latency with TFTP). Something to think about... doing simple reassembly (only handle in-sequence reassembly) is fairly simple.
