28.Dt MSK 4 29.Os 30.Sh NAME 31.Nm msk 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 70The 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 85.Cm full-duplex 86or 87.Cm half-duplex 88modes. 89.It Cm 100baseTX 90Set 100Mbps (Fast Ethernet) operation. 91The 92.Xr ifconfig 8 93.Cm mediaopt 94option can also be used to select either 95.Cm full-duplex 96or 97.Cm half-duplex 98modes. 99.It Cm 1000baseTX 100Set 1000baseTX operation over twisted pair. 101The 102.Xr ifconfig 8 103.Cm mediaopt 104option can also be used to select either 105.Cm full-duplex 106or 107.Cm half-duplex 108modes. 109.It Cm 1000baseSX 110Set 1000Mbps (Gigabit Ethernet) operation. 111Both 112.Cm full-duplex 113and 114.Cm half-duplex 115modes are supported. 116.El 117.Pp 118The 119.Nm 120driver supports the following media options: 121.Bl -tag -width ".Cm full-duplex" 122.It Cm full-duplex 123Force full duplex operation. 124.It Cm half-duplex 125Force half duplex operation. 126.El 127.Pp 128For more
