Dell PowerEdge R820 Broadcom BCM57800 support

[John]

Hi Folks,

   I have an R820 I'm testing. The system seems to boot up fine, but
no network adapters show up. From pciconf -l :

none4 at pci0:1:0:0:       class=0x020000 card=0x1f5c1028 chip=0x168a14e4 rev=0x10 hdr=0x00
none5 at pci0:1:0:1:       class=0x020000 card=0x1f5c1028 chip=0x168a14e4 rev=0x10 hdr=0x00
none6 at pci0:1:0:2:       class=0x020000 card=0x1f671028 chip=0x168a14e4 rev=0x10 hdr=0x00
none7 at pci0:1:0:3:       class=0x020000 card=0x1f671028 chip=0x168a14e4 rev=0x10 hdr=0x00

which appears to be these:

Broadcom BCM57800 NetXtreme II 10 GigE   1f5c
Broadcom BCM57800 NetXtreme II 1 GigE    1f67

Does anyone have any experience with these?

Thanks,
John
