Whoa ... ok, so now I've run into something horrible.
According to dmidecode, a Dell R410 has a Broadcom 5716 chipset on it.
On Board Device 2 Information
Type: Ethernet
Status: Enabled
Description: Embedded Broadcom 5716 NIC 1
On Board Device 3 Information
Type: Ethernet
Status: Enabled
Description: Embedded Broadcom 5716 NIC 2
However, when I ask the chipset what type it is via:
if_bcereg.h:#define BCE_CHIP_NUM(sc)
It clearly indicates that it is a 5709???? What on earth is going on
here? The following patch, yeilds the following output:
