NAME
msk
- Marvell/SysKonnect Yukon II Gigabit Ethernet adapter driver
SYNOPSIS
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
device miibusdevice msk
Alternatively, to load the driver as a
module at boot time, place the following line in
loader.conf5:
if_msk_load="YES"
DESCRIPTION
The
device driver provides support for various NICs based on the
Marvell/SysKonnect Yukon II Gigabit Ethernet controller chip.
All NICs supported by the
driver have TCP/UDP/IP checksum offload for transmit, TCP
segmentation offload (TSO), hardware VLAN tag stripping/insertion
features and an interrupt moderation mechanism as well as a 64-bit
multicast hash filter.
The Yukon II supports TBI (ten bit interface) and GMII
transceivers, which means it can be used with either copper or
1000baseX fiber applications.
The Yukon II also supports Jumbo Frames (up to 9022 bytes), 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
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
rc.conf5.
10baseT/UTP
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.
1000baseTX
Set 1000baseTX operation over twisted pair.
The
ifconfig(8)
mediaopt
option can also be used to select either
full-duplex
or
half-duplex
modes.
1000baseSX
Set 1000Mbps (Gigabit Ethernet) operation.
Both
full-duplex
and
half-duplex
modes are supported.
The
driver supports the following media options:
full-duplex
Force full duplex operation.
half-duplex
Force half duplex operation.
The
driver also supports one special link option for 1000baseTX cards:
link0
With 1000baseTX cards, establishing a link between two ports requires
that one port is configured as master and the other one as slave.
With autonegotiation,
the master/slave settings will be chosen automatically.
However when manually selecting the link state, it is necessary to
force one side of the link to be a master and the other a slave.
The
driver configures the ports as slaves by default.
Setting the
link0
flag with
ifconfig(8)
will set a port as a master instead.
For more information on configuring this device, see
ifconfig(8).

LOADER TUNABLES
Tunables can be set at the
loader(8)
prompt before booting the kernel or stored in
loader.conf5.
hw.msk.msi_disable
This tunable disables MSI support on the Ethernet hardware.
The default value is 0.
SYSCTL VARIABLES
The following variables are available as both
sysctl(8)
variables and
loader(8)
tunables:
dev.mskc.%d.process_limit
Maximum amount of Rx events to be processed in the event loop before
rescheduling a taskqueue.
The accepted range is 30 to 256, the default value is 128 events.
The interface does not need to be brought down and up again before
a change takes effect.
The
driver was written by
An Pyun YongHyeon
Aq yongari@FreeBSD.org
and it is based on
sk(4)
and Marvell's
Fx driver.
It first appeared in
Fx 7.0
and
Fx 6.3 .
