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
56 driver have TCP/UDP/IP checksum offload for transmit, TCP
57 segmentation offload (TSO), hardware VLAN tag stripping/insertion
58 features and an interrupt moderation mechanism as well as a 64-bit
59 multicast hash filter.
60 The Yukon II supports TBI (ten bit interface) and GMII
61 transceivers, which means it can be used with either copper or
62 1000baseX fiber applications.
64 The Yukon II also supports Jumbo Frames (up to 9022 bytes), which can be
65 configured via the interface MTU setting.
66 Selecting an MTU larger than 1500 bytes with the
68 utility configures the adapter to receive and transmit Jumbo Frames.
72 driver supports the following media types:
73 .Bl -tag -width ".Cm 10baseT/UTP"
75 Enable autoselection of the media type and options.
76 The user can manually override
77 the autoselected mode by adding media options to
84 option can also be used to select either
90 Set 100Mbps (Fast Ethernet) operation.
94 option can also be used to select either
100 Set 1000baseTX operation over twisted pair.
104 option can also be used to select either
110 Set 1000Mbps (Gigabit Ethernet) operation.
120 driver supports the following media options:
121 .Bl -tag -width ".Cm full-duplex"
123 Force full duplex operation.
125 Force half duplex operation.

205 Tunables can be set at the
207 prompt before booting the kernel or stored in
209 .Bl -tag -width indent
210 .It Va hw.msk.msi_disable
211 This tunable disables MSI support on the Ethernet hardware.
212 The default value is 0.
215 The following variables are available as both
220 .Bl -tag -width indent
221 .It Va dev.mskc.%d.int_holdoff
222 Maximum number of time to delay interrupts.
223 The valid range is 0 to 34359738 for 125MHz clock in units of 1us,
224 the default is 100 (100us).
225 The interface need to be brought down and up again before a change
227 .It Va dev.mskc.%d.process_limit
228 Maximum amount of Rx events to be processed in the event loop before
229 rescheduling a taskqueue.
230 The accepted range is 30 to 256, the default value is 128 events.
231 The interface does not need to be brought down and up again before
232 a change takes effect.
