The boxes (3650s) came with Broadcom BCM5708 on-board, but I push most=20
of my traffic over these:
1c:00.1 Ethernet controller: Intel Corporation 82571EB Gigabit Ethernet=20
Controller (rev 06)
Subsystem: Intel Corporation PRO/1000 PT Dual Port Server Adapter=
Flags: bus master, fast devsel, latency 0, IRQ 58
Memory at c7ea0000 (32-bit, non-prefetchable) [size=3D128K]
Memory at c7e80000 (32-bit, non-prefetchable) [size=3D128K]
I/O ports at 6020 [size=3D32]
Capabilities: [c8] Power Management version 2
Capabilities: [d0] Message Signalled Interrupts: 64bit+=20
Queue=3D0/0 Enable+
Capabilities: [e0] Express Endpoint IRQ 0
Capabilities: [100] Advanced Error Reporting
There are four Intel ports in the boxes, so traffic may or may not stay=20
on the same PCI-X card depending how things are flowing.
