The
fxp
driver provides support for Ethernet adapters based on the Intel
i82557, i82558, i82559, i82550, and i82562 chips.
The driver supports TCP/UDP/IP checksum offload for both transmit
and receive on i82550 and i82551.
On i82559 only TCP/UDP checksum offload for receive is supported.
TCP segmentation offload (TSO) for IPv4 as well as VLAN hardware
tag insertion/stripping is supported on i82550 and i82551.
Wake On Lan (WOL) support is provided on all controllers
except i82557, i82259ER and early i82558 revisions.
The
fxp
driver supports the following media types:
|
| autoselect
|
Enable autoselection of the media type and options.
The autoselected mode can be overridden by adding the media options to
rc.conf(5).
|
| 10baseT/UTP
|
| |
Set 10Mbps operation.
|
| 100baseTX
|
Set 100Mbps (Fast Ethernet) operation.
|
|
The
fxp
driver supports the following media options:
| full-duplex
|
| |
Force full duplex operation.
|
| half-duplex
|
| |
Force half duplex operation.
|
|
Note that 100baseTX media type is not available on the Pro/10.
For further information on configuring this device, see
ifconfig(8).
The
fxp
driver supports reception and transmission of extended frames
for
vlan(4).
This capability of
fxp
can be controlled by means of the
vlanmtu
parameter
to
ifconfig(8).
The
fxp
driver also supports a special link option:
| link0
|
Some chip revisions have loadable microcode which can be used to reduce the
interrupt load on the host cpu.
Not all boards have microcode support.
Setting the
link0
flag with
ifconfig(8)
will download the microcode to the chip if it is available.
