Hi I am playing with jumbo frames in vblade, which uses write(2) on BPF to put it's raw AoE packets onto ethernet. The problem I am having is with jumbo frames; when the write is greater than 4K it fails with I/O error. Is this tweakable or fundamental? I have tried ramping up net.raw.* from 8K to 32K; no joy thanks Andrew Basterfield
