32 .Nd Marvell/SysKonnect Yukon II Gigabit Ethernet adapter driver
34 To compile this driver into the kernel,
35 place the following lines in your
36 kernel configuration file:
37 .Bd -ragged -offset indent
42 Alternatively, to load the driver as a
43 module at boot time, place the following line in
45 .Bd -literal -offset indent
51 device driver provides support for various NICs based on the
52 Marvell/SysKonnect Yukon II Gigabit Ethernet controller chip.
54 All NICs supported by the
58 .\"TCP/UDP/IP checksum offload for transmit,
59 .\"TCP segmentation offload (TSO),
60 .\"hardware VLAN tag stripping/insertion features and
61 an interrupt moderation mechanism as well as a 64-bit multicast hash filter.
62 The Yukon II supports TBI (ten bit interface) and GMII
63 transceivers, which means it can be used with either copper or
64 1000baseX fiber applications.
67 .\"The Yukon II also supports Jumbo Frames (up to 9022 bytes), which can be
68 .\"configured via the interface MTU setting.
69 .\"Selecting an MTU larger than 1500 bytes with the
71 .\"utility configures the adapter to receive and transmit Jumbo Frames.
75 driver supports the following media types:
76 .Bl -tag -width ".Cm 10baseT/UTP"
78 Enable autoselection of the media type and options.
79 The user can manually override
80 the autoselected mode by adding media options to
87 option can also be used to select either
93 Set 100Mbps (Fast Ethernet) operation.
97 option can also be used to select either
103 Set 1000baseT operation over twisted pair.
107 option can also be used to select either
113 Set 1000Mbps (Gigabit Ethernet) operation.
123 driver supports the following media options:
124 .Bl -tag -width ".Cm full-duplex"
126 Force full duplex operation.
128 Force half duplex operation.
133 driver also supports one special link option for 1000baseT cards:
134 .Bl -tag -width ".Cm link0"
136 With 1000baseT cards, establishing a link between two ports requires
137 that one port is configured as master and the other one as slave.
138 With autonegotiation,
139 the master/slave settings will be chosen automatically.
140 However when manually selecting the link state, it is necessary to
141 force one side of the link to be a master and the other a slave.
144 driver configures the ports as slaves by default.
149 will set a port as a master instead.
