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 miibus
device msk
Alternatively, to load the driver as a module at boot time, place the following
line in
loader.conf(5):
DESCRIPTION¶
The
msk
device driver provides support for
various NICs based on the Marvell/SysKonnect Yukon II Gigabit Ethernet
controller chip.
All NICs supported by the
msk
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
msk
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.conf(5).
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
msk
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).

LOADER TUNABLES¶
Tunables can be set at the
loader(8) prompt before
booting the kernel or stored in
loader.conf(5).
- 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.int_holdoff
- Maximum number of time to delay interrupts. The valid range is 0 to
34359738 for 125MHz clock in units of 1us, the default is 100 (100us). The
interface need to be brought down and up again before a change takes
effect.
- 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.

HISTORY¶
The
msk
driver was written by
Pyun YongHyeon
⟨yongari@FreeBSD.org⟩ and it is based on
sk(4) and Marvell's
FreeBSD driver. It first appeared in
FreeBSD 7.0 and
FreeBSD
6.3.
