config NET_VENDOR_BROADCOM
bool "Broadcom devices"
depends on (SSB_POSSIBLE && HAS_DMA) || PCI || BCM63XX || \
SIBYTE_SB1xxx_SOC
---help---
If you have a network (Ethernet) chipset belonging to this class,
say Y.
Note that the answer to this question does not directly affect
the kernel: saying N will just case the configurator to skip all
the questions regarding AMD chipsets. If you say Y, you will be asked
for your specific chipset/driver in the following questions.
if NET_VENDOR_BROADCOM
config B44
tristate "Broadcom 440x/47xx ethernet support"
depends on SSB_POSSIBLE && HAS_DMA
select SSB
select MII
---help---
If you have a network (Ethernet) controller of this type, say Y
or M and read the Ethernet-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
To compile this driver as a module, choose M here. The module
will be called b44.

select MII
select PHYLIB
help
This driver supports the ethernet MACs in the Broadcom 63xx
MIPS chipset family (BCM63XX).
config BNX2
tristate "Broadcom NetXtremeII support"
depends on PCI
select CRC32
select FW_LOADER
---help---
This driver supports Broadcom NetXtremeII gigabit Ethernet cards.
To compile this driver as a module, choose M here: the module
will be called bnx2. This is recommended.
config CNIC
tristate "Broadcom CNIC support"
depends on PCI
select BNX2
select UIO
---help---
This driver supports offload features of Broadcom NetXtremeII
gigabit Ethernet cards.
To compile this driver as a module, choose M here: the module
will be called cnic. This is recommended.
config SB1250_MAC
tristate "SB1250 Gigabit Ethernet support"
depends on SIBYTE_SB1xxx_SOC
select PHYLIB
---help---
This driver supports Gigabit Ethernet interfaces based on the
Broadcom SiByte family of System-On-a-Chip parts. They include
the BCM1120, BCM1125, BCM1125H, BCM1250, BCM1255, BCM1280, BCM1455
and BCM1480 chips.
To compile this driver as a module, choose M here: the module
will be called sb1250-mac.
config TIGON3
tristate "Broadcom Tigon3 support"
depends on PCI
select PHYLIB
---help---
This driver supports Broadcom Tigon3 based gigabit Ethernet cards.
To compile this driver as a module, choose M here: the module
will be called tg3. This is recommended.
config BNX2X
tristate "Broadcom NetXtremeII 10Gb support"
depends on PCI
select FW_LOADER
select ZLIB_INFLATE
select LIBCRC32C
select MDIO
---help---
This driver supports Broadcom NetXtremeII 10 gigabit Ethernet cards.
To compile this driver as a module, choose M here: the module
will be called bnx2x. This is recommended.
