The
bge driver supports IPv4 IP, TCP, and UDP checksum offload
for receive, IP checksum offload for transmit, VLAN tag insertion and
stripping, as well as a 256-bit multicast hash filter. The BCM5717, BCM5718,
BCM5723, BCM5754, BCM5755, BCM5761, BCM5764, BCM5784, BCM5785, BCM5787 and
BCM577xx chips also support IPv6 receive TCP/UDP checksum offload. The
bge driver supports this feature of the chip. See
ifconfig(8) for information on
how to enable this feature.
The BCM5700, BCM5701, BCM5702, BCM5703, BCM5704, BCM5714, BCM5717, BCM5719,
BCM5720, BCM5780, BCM57765 and BCM57766 also support jumbo frames, which can
be configured via the interface MTU setting. Selecting an MTU larger than 1500
bytes with the
ifconfig(8)
utility configures the adapter to receive and transmit Jumbo frames.
The level of interrupt mitigation for received packets can be adjusted with the
hw.bge.rx_lvl
sysctl(8) control. A value of 1
yields a
bge interrupt for every two full-sized Ethernet
frames. Each increment of the value will, roughly, halve receive interrupt
rate, up to a maximum of 5, which interrupts about every 30 to 40 full-sized
TCP segments.
The
bge driver supports the following media types:
-
-
- autoselect
- Enable autoselection of the media type and options. The
user can manually override the autoselected mode by adding media options
to the appropriate
ifconfig.if(5)
file.
-
-
- 10baseT
- Set 10Mbps operation. The
ifconfig(8)
mediaopt option can also be used to select either
full-duplex or half-duplex modes.
-
-
- 100baseTX
- Set 100Mbps (Fast Ethernet) operation. The
ifconfig(8)
mediaopt option can also be used to select either
full-duplex or half-duplex modes.
-
-
- 1000baseT
- Set 1000baseT operation over twisted pair. Both
full-duplex and half-dupex modes are
supported.
-
-
- 1000baseSX
- Set 1000Mbps (Gigabit Ethernet) operation. Both
full-duplex and half-duplex modes are
supported.
The
bge driver supports the following media options:
-
-
- full-duplex
- Force full duplex operation.
-
-
- half-duplex
- Force half duplex operation.
For more information on configuring this device, see
ifconfig(8).
DIAGNOSTICS
- bge%d: can't find mem space
- A fatal initialization error has occurred.
- bge%d: couldn't map interrupt
- A fatal initialization error has occurred.
- bge%d: watchdog timeout --
resetting
- The device has stopped responding to the network, or there
is a problem with the network connection (cable).
