I suggest that you examine your MTU.

At least one older version of the NI5210 packet driver could not
accept a packet larger than 1024 bytes. When the later versions
of CUTCP came along, we internally supported a 1500 byte MTU, which
would result in a crashed PC if the broken packet driver was used.

I suggest trying an MTU of 512 and seeing how that effects things.
