... I had a 410 in to test, and I do believe it uses a different 
broadcom chip.  This is one from an R710, as shown in lspci:

01:00.0 Ethernet controller: Broadcom Corporation NetXtreme II BCM5709 
Gigabit Ethernet (rev 20)

I think yours will be a BCM 5716, and I'm not able to comment on how the 
drivers are for that chip.

Cheers. Tom.
