- Sun Blade 10 Gigabit Ethernet network driver

Synopsis

/dev/hxge*

Description

The hxge Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based STREAMS driver supporting the Data Link Provider Interface, dlpi(7P), on the Sun Blade Shared 10Gb Ethernet Interface.

The Shared PCI-Express 10 Gb networking interface provides network I/O consolidation for up to six Constellation blades, with each blade seeing its own portion of the network interface.

The hxge driver functions include chip initialization, frame transmit and receive, flow classification, multicast and promiscuous support and error recovery and reporting in the blade domain.

APPLICATION PROGRAMMING INTERFACE

The cloning character-special device, /dev/hxge, is used to access Sun Blade Shared 10Gb Ethernet Interface devices installed within the system.

The hxge driver is managed by the dladm(1M) command line utility, which allows VLANs to be defined on top of hxge instances and for hxge instances to be aggregated. See dladm(1M) for more details.

You must send an explicit DL_ATTACH_REQ message to associate the opened stream with a particular device (PPA). The PPA ID is interpreted as an unsigned integer data type and indicates the corresponding device instance (unit) number. The driver returns an error (DL_ERROR_ACK) if the PPA field value does not correspond to a valid device instance number for the system. The device is initialized on first attach and de-initialized (stopped) at last detach

The values returned by the driver in the DL_INFO_ACK primitive in response to a DL_INFO_REQ are:

Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular Service Access Point (SAP) with the stream.

CONFIGURATION

The link speed and mode are fixed at 10 Gbps full-duplex.

The default MTU is 1500. To enable jumbo frame support, you configure the hxge driver by defining the accept-jumbo property to 1 in the hxge.conf file. Note that the largest jumbo size is 9178 bytes.

The driver may be configured to discard certain classes of traffic. By default, no class of traffic is allowed. You configure the hxge driver by defining the class option property to 0x20000 in hxge.conf to discard the specified class of traffic. For example, the following line in hxge.conf discards all IP Version 4 TCP traffic:

class-opt-ipv4-tcp = 0x20000;

You can also use the ndd(1M) command to configure the hxge driver at runtime to discard any classes of traffic.

The hxgedriver supports the self-healing functionality of Solaris OS. By default it is configured to DDI_FM_EREPORT_CAPABLE | DDI_FM_ERRCB_CAPABLE. You configure the hxge driver by defining the fm-capable property in hxge.conf to other capabilities or to 0x0 to disable it entirely.

The hxge driver may be configured using the standard ifconfig(1M) command.

The hxge driver also reports various hardware and software statistics data. You can view these statistics using the kstat(1M) command.
