Oh, I just noticed you mention "jumbo" in your subject line. The above
bug report is an issue related to TSO segments. I have no idea if there
is a separate problem w.r.t. the driver handling jumbo packets. (I believe
that all using a jumbo packet would imply is that the TSO segment would
be broken into fewer mtu sized packets by the hardware, so enabling
jumbo packets shouldn't affect this.)
