Dell Broadcom NetXtreme Family of Adapters User Manual page 28

The following are optional custom keywords used in the Net.cfg file:
BUSNUM
DEVNUM
FUNNUM
SUBVID
MODEL
The first two keywords (BUSNUM and DEVNUM) are used concurrently and have been included for manufacturing purposes.
Do not use them unless you are familiar with PCI device configuration. These two keywords are needed if multiple Broadcom
NetXtreme Gigabit Ethernet adapters are installed in a system, and each adapter must be loaded in a specific order.
BUSNUM specifies the PCI bus number and DEVNUM specifies the device number that is assigned to the adapter when it is
configured by the PCI BIOS.
The values for these adapter parameters are displayed in hexadecimal notation when the driver loads (the Net.cfg file expects
hexadecimal values). A PCI device scan utility can also be used to find this information. If the driver loads on a single
adapter, the displayed values can be used in the Net.cfg file.
If a PCI scan utility displays adapter 1 at bus 4 and device 11 (hexadecimal), and adapter 3 at bus 3 and device 13
(hexadecimal), the following load instructions are written to the Net.cfg file (load adapter 3 first, and optionally load adapter 1
second):
LINK DRIVER B57
BUSNUM 3
DEVNUM 13 (13 hex = 19 decimal)
LINK DRIVER B57
BUSNUM 4
DEVNUM 11 (11 hex = 17 decimal)
The FUNNUM keyword is used to determine which function/port the driver is to load on when using a multifunction (multiport)
adapter. Function number values are limited to 0 and 1, for the first and second ports of the adapter.
The SUBVID keyword is used to for load the driver only on the first adapter found that has a subvendor ID (SVID) that
matches the one set in Net.cfg. The driver ignores all other adapters that do not have a matching SVID. SUBVID expects a
hexadecimal number.
Example:
LINK DRIVER B57
SUBVID 14E4
SUBVID cannot be used with BUSNUM, DEVNUM or FUNNUM.
The MODEL keyword is for loading the driver only on the first adapter found that has a subvendor ID (SVID) that matches the
one set in MODEL. The driver ignores all other adapters that do not have a matching SVID. MODEL expects a decimal
number.
Example:
LINK DRIVER B44
MODEL 534
