1 IXGBE(7D) Devices IXGBE(7D) 2 3 4 5 NAME 6 ixgbe - Intel 10Gb PCI Express NIC Driver 7 8 SYNOPSIS 9 /dev/ixgbe* 10 11 12 DESCRIPTION 13 The ixgbe 10 Gigabit Ethernet driver is a multi-threaded, loadable, 14 clonable, GLD-based STREAMS driver supporting the Data Link Provider 15 Interface, dlpi(7P), on Intel 10-Gigabit PCI Express Ethernet 16 controllers. 17 18 19 The ixgbe driver functions include controller initialization, frame 20 transmit and receive, promiscuous and multicast support, and error 21 recovery and reporting. 22 23 24 The ixgbe driver supports the following Intel 10-Gigabit PCI Express 25 Ethernet controllers: 26 27 o Intel Ethernet Controller 82598EB Family 28 29 o Intel Ethernet Controller 82599EB (X520) Family 30 31 o Intel Ethernet Controller X540 Family 32 33 o Intel Ethernet Controller X550 Family 34 35 The ixgbe driver and hardware support auto-negotiation, a protocol 36 specified by the IEEE 802.3ae specification. 37 38 APPLICATION PROGRAMMING INTERFACE 39 The cloning character-special device, /dev/ixgbe, is used to access all 40 Intel 10-Gigabit PCI Express Ethernet devices installed within the 41 system. 42 43 44 The ixgbe driver is managed by the dladm(1M) command line utility, 45 which allows VLANs to be defined on top of ixgbe instances and for 46 ixgbe instances to be aggregated. See dladm(1M) for more details. 47 48 49 You must send an explicit DL_ATTACH_REQ message to associate the opened 50 stream with a particular device (PPA). The PPA ID is interpreted as an 51 unsigned integer data type and indicates the corresponding device 52 instance (unit) number. The driver returns an error (DL_ERROR_ACK) if 53 the PPA field value does not correspond to a valid device instance 54 number for the system. The device is initialized on first attach and 55 de-initialized (stopped) at last detach. 56 57 58 The values returned by the driver in the DL_INFO_ACK primitive in 59 response to your DL_INFO_REQ are: 60 61 o Maximum SDU for Intel 82598EB is 16366. 62 63 o Maximum SDU for Intel 82599EB, X540 and X550 is 15500. 64 65 o Minimum SDU is 0. 66 67 o DLSAP address length is 8. 68 69 o MAC type is DL_ETHER. 70 71 o SAP (Service Access Point) length value is -2, meaning the 72 physical address component is followed immediately by a 73 2-byte SAP component within the DLSAP address. 74 75 o Broadcast address value is the Ethernet/IEEE broadcast 76 address (FF:FF:FF:FF:FF:FF). 77 78 Once in the DL_ATTACHED state, you must send a DL_BIND_REQ 79 to associate a particular SAP with the stream. 80 81 CONFIGURATION 82 By default, the ixgbe driver performs auto-negotiation to select the 83 link speed and mode. Link speed and mode can only be 10000 Mbps full- 84 duplex for fiber, and only 10000, 1000, or 100 Mbps full-duplex for 85 copper. See the IEEE802.3 standard for more information. 86 87 FILES 88 /dev/ixgbe* 89 Special character device. 90 91 92 /kernel/drv/amd64/ixgbe 93 Device driver (x86) 94 95 96 /kernel/drv/sparcv9/ixgbe 97 Device driver (SPARC) 98 99 100 /kernel/drv/ixgbe.conf 101 Driver configuration file 102 103 104 ATTRIBUTES 105 See attributes(5) for descriptions of the following attributes: 106 107 108 109 110 +--------------------+-----------------+ 111 | ATTRIBUTE TYPE | ATTRIBUTE VALUE | 112 +--------------------+-----------------+ 113 |Architecture | SPARC, x86 | 114 +--------------------+-----------------+ 115 |Interface Stability | Committed | 116 +--------------------+-----------------+ 117 118 SEE ALSO 119 dladm(1M), netstat(1M), driver.conf(4), attributes(5), streamio(7I), 120 dlpi(7P) 121 122 123 Writing Device Drivers 124 125 126 STREAMS Programming Guide 127 128 129 Network Interfaces Programmer's Guide 130 131 132 IEEE 802.3ae Specification, IEEE - 2002 133 134 135 136 January 10, 2020 IXGBE(7D)
