MSK(4) Kernel Interfaces Manual MSK(4) NAME msk -- Marvell/SysKonnect Yukon II Gigabit Ethernet adapter driver SYNOPSIS To compile this driver into the kernel, place the following lines in your kernel configuration file: device miibus device msk Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5): if_msk_load="YES" DESCRIPTION The msk device driver provides support for various NICs based on the Mar- vell/SysKonnect Yukon II Gigabit Ethernet controller chip. All NICs supported by the msk driver have TCP/UDP/IP checksum offload for transmit, TCP segmentation offload (TSO), hardware VLAN tag stripping/in- sertion features and an interrupt moderation mechanism as well as a 64-bit multicast hash filter. The Yukon II supports TBI (ten bit interface) and GMII transceivers, which means it can be used with either copper or 1000ba- seX fiber applications. The Yukon II also supports Jumbo Frames (up to 9022 bytes), which can be configured via the interface MTU setting. Selecting an MTU larger than 1500 bytes with the ifconfig(8) utility configures the adapter to receive and transmit Jumbo Frames. The msk driver supports the following media types: autoselect Enable autoselection of the media type and options. The user can manually override the autoselected mode by adding media options to rc.conf(5). 10baseT/UTP Set 10Mbps operation. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes. 100baseTX Set 100Mbps (Fast Ethernet) operation. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes. 1000baseTX Set 1000baseTX operation over twisted pair. The ifconfig(8) mediaopt option can also be used to select either full-duplex or half-duplex modes. 1000baseSX Set 1000Mbps (Gigabit Ethernet) operation. Both full-duplex and half-duplex modes are supported. The msk driver supports the following media options: full-duplex Force full duplex operation. half-duplex Force half duplex operation. The msk driver also supports one special link option for 1000baseTX cards: link0 With 1000baseTX cards, establishing a link between two ports re- quires that one port is configured as master and the other one as slave. With autonegotiation, the master/slave settings will be cho- sen automatically. However when manually selecting the link state, it is necessary to force one side of the link to be a master and the other a slave. The msk driver configures the ports as slaves by de- fault. Setting the link0 flag with ifconfig(8) will set a port as a master instead. For more information on configuring this device, see ifconfig(8). HARDWARE The msk driver provides support for various NICs based on the Mar- vell/SysKonnect Yukon II based Gigabit Ethernet controller chips, includ- ing: * D-Link 550SX Gigabit Ethernet * D-Link 560T Gigabit Ethernet * Marvell Yukon 88E8021CU Gigabit Ethernet * Marvell Yukon 88E8021 SX/LX Gigabit Ethernet * Marvell Yukon 88E8022CU Gigabit Ethernet * Marvell Yukon 88E8022 SX/LX Gigabit Ethernet * Marvell Yukon 88E8061CU Gigabit Ethernet * Marvell Yukon 88E8061 SX/LX Gigabit Ethernet * Marvell Yukon 88E8062CU Gigabit Ethernet * Marvell Yukon 88E8062 SX/LX Gigabit Ethernet * Marvell Yukon 88E8035 Gigabit Ethernet * Marvell Yukon 88E8036 Gigabit Ethernet * Marvell Yukon 88E8038 Gigabit Ethernet * Marvell Yukon 88E8039 Gigabit Ethernet * Marvell Yukon 88E8050 Gigabit Ethernet * Marvell Yukon 88E8052 Gigabit Ethernet * Marvell Yukon 88E8053 Gigabit Ethernet * Marvell Yukon 88E8055 Gigabit Ethernet * Marvell Yukon 88E8056 Gigabit Ethernet * Marvell Yukon 88E8058 Gigabit Ethernet * SysKonnect SK-9Sxx Gigabit Ethernet * SysKonnect SK-9Exx Gigabit Ethernet LOADER TUNABLES Tunables can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5). hw.msk.msi_disable This tunable disables MSI support on the Ethernet hardware. The default value is 0. SYSCTL VARIABLES The following variables are available as both sysctl(8) variables and loader(8) tunables: dev.mskc.%d.process_limit Maximum amount of Rx events to be processed in the event loop be- fore rescheduling a taskqueue. The accepted range is 30 to 256, the default value is 128 events. The interface does not need to be brought down and up again before a change takes effect.

It first appeared in FreeBSD 7.0 and FreeBSD 6.3. FreeBSD 7.2 December 5, 2007 MSK(4)
