Intel i350-T4 not recognized

Hey folks,

Just installed a new NIC, Intel i350-T4.  esxcfg-nics -l does not show the NIC, but lspci shows this:

0e:00.0 Ethernet controller: Intel Corporation Unknown device 1521 (rev 01)
0e:00.1 Ethernet controller: Intel Corporation Unknown device 1521 (rev 01)
0e:00.2 Ethernet controller: Intel Corporation Unknown device 1521 (rev 01)
0e:00.3 Ethernet controller: Intel Corporation Unknown device 1521 (rev 01)

Any suggestions for getting this recognized by ESX?

Thanks,

Grant
