Hi Dave,
This is a 82571 low profile quad-port copper card, right? The e1000g
driver supports jumbo frames for the 82571 chipset quite well. This
problem is not supposed to happen.
Could you please run the following dtrace script on your system to
check the max_frame_size of the driver?
% dtrace -n "e1000g_local_timer:entry{adapter=(struct e1000g *)arg0;
printf(\"max_frame_size=%d\",adapter->shared.mac.max_frame_size)}"
Thanks,
Ted
