17 ASPM/Jumbo Frames Disabled Due to Early Receive Threshold Overrun
Buffer
Status: Intel does not plan to resolve this erratum in the 82573
Gigabit Ethernet Controller. Jumbo frames is not supported in
82573E/V & is supported with the workaround above in 82573L.
You'll have to use different hardware. The chipset you've got has a
bug, and jumbo frame support is disabled as a result.
