Intel 82559ER network card

I have an Intel 82559ER network card. When I run nicinfo I get
NOT GONNA WORK Ethernet Controller
Is this a problem, or can it be safely ignored? I’m using the patched speedo
driver that was made available (file length is 47698 bytes). Does the 6.2
driver support the 82559ER?

The relevant output of ‘pci -v’ is
Class = Network (Ethernet)
Vendor ID = 8086h, Intel Corporation
Device ID = 1209h, 82559ER
PCI index = 0h
Class Codes = 020000h
Revision ID = 9h
