32.Nd Marvell/SysKonnect Yukon II Gigabit Ethernet adapter driver
33.Sh SYNOPSIS
34To compile this driver into the kernel,
35place the following lines in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "device miibus"
39.Cd "device msk"
40.Ed
41.Pp
42Alternatively, to load the driver as a
43module at boot time, place the following line in
44.Xr loader.conf 5 :
45.Bd -literal -offset indent
46if_msk_load="YES"
47.Ed
48.Sh DESCRIPTION
49The
50.Nm
51device driver provides support for various NICs based on the
52Marvell/SysKonnect Yukon II Gigabit Ethernet controller chip.
53.Pp
54All NICs supported by the
55.Nm
56driver have TCP/UDP/IP checksum offload for transmit, TCP
57segmentation offload (TSO), hardware VLAN tag stripping/insertion
58features and an interrupt moderation mechanism as well as a 64-bit
59multicast hash filter.
60The Yukon II supports TBI (ten bit interface) and GMII
61transceivers, which means it can be used with either copper or
621000baseX fiber applications.
63.Pp
64The Yukon II also supports Jumbo Frames (up to 9022 bytes), which can be
65configured via the interface MTU setting.
66Selecting an MTU larger than 1500 bytes with the
67.Xr ifconfig 8
68utility configures the adapter to receive and transmit Jumbo Frames.
69.Pp

71.Nm
72driver supports the following media types:
73.Bl -tag -width ".Cm 10baseT/UTP"
74.It Cm autoselect
75Enable autoselection of the media type and options.
76The user can manually override
77the autoselected mode by adding media options to
78.Xr rc.conf 5 .
79.It Cm 10baseT/UTP
80Set 10Mbps operation.
81The
82.Xr ifconfig 8
83.Cm mediaopt
84option can also be used to select either

86or
87.Cm half-duplex
88modes.

128The
129.Nm
130driver also supports one special link option for 1000baseTX cards:
131.Bl -tag -width ".Cm link0"
132.It Cm link0
133With 1000baseTX cards, establishing a link between two ports requires
134that one port is configured as master and the other one as slave.
135With autonegotiation,
136the master/slave settings will be chosen automatically.
137However when manually selecting the link state, it is necessary to
138force one side of the link to be a master and the other a slave.
139The
140.Nm
141driver configures the ports as slaves by default.
142Setting the
143.Cm link0
144flag with
145.Xr ifconfig 8
146will set a port as a master instead.
