33 .Nd Marvell/SysKonnect Yukon II Gigabit Ethernet adapter driver
35 To compile this driver into the kernel,
36 place the following lines in your
37 kernel configuration file:
38 .Bd -ragged -offset indent
43 Alternatively, to load the driver as a
44 module at boot time, place the following line in
46 .Bd -literal -offset indent
52 device driver provides support for various NICs based on the
53 Marvell/SysKonnect Yukon II Gigabit Ethernet controller chip.
55 All NICs supported by the
59 .\"TCP/UDP/IP checksum offload for transmit,
60 .\"TCP segmentation offload (TSO),
61 .\"hardware VLAN tag stripping/insertion features and
62 an interrupt moderation mechanism as well as a 64-bit multicast hash filter.
63 The Yukon II supports TBI (ten bit interface) and GMII
64 transceivers, which means it can be used with either copper or
65 1000baseX fiber applications.
68 .\"The Yukon II also supports Jumbo Frames (up to 9022 bytes), which can be
69 .\"configured via the interface MTU setting.
70 .\"Selecting an MTU larger than 1500 bytes with the
72 .\"utility configures the adapter to receive and transmit Jumbo Frames.
76 driver supports the following media types:
77 .Bl -tag -width ".Cm 10baseT/UTP"
79 Enable autoselection of the media type and options.
80 The user can manually override
81 the autoselected mode by adding media options to
88 option can also be used to select either
94 Set 100Mbps (Fast Ethernet) operation.
98 option can also be used to select either
104 Set 1000baseT operation over twisted pair.
108 option can also be used to select either
114 Set 1000Mbps (Gigabit Ethernet) operation.
124 driver supports the following media options:
125 .Bl -tag -width ".Cm full-duplex"
127 Force full duplex operation.
129 Force half duplex operation.
134 driver also supports one special link option for 1000baseT cards:
135 .Bl -tag -width ".Cm link0"
137 With 1000baseT cards, establishing a link between two ports requires
138 that one port is configured as master and the other one as slave.
139 With autonegotiation,
140 the master/slave settings will be chosen automatically.
141 However when manually selecting the link state, it is necessary to
142 force one side of the link to be a master and the other a slave.
145 driver configures the ports as slaves by default.
150 will set a port as a master instead.
