Good, that's a start. Now, is there a switch of some sort involved or are
you going
back to back? Some switches have problems with jumbo frames, there are also
some vendors (including our's) interfaces that do not support jumbo frames,
so
you need to check on that also (I mean the RT).
I will check on the Intel adapter tomorrow.
