- Neterion X3100 10 Gigabit Ethernet Driver
The vxge 10–Gigabit Ethernet driver is a multi-threaded, loadable, clonable, GLD-based, STREAMS driver that supports the Data Link Provider Interface, dlpi(7P), on Neterion X3100 10-Gigabit Ethernet controllers.
The vxge driver functions include controller initialization, frame transmit and receive, promiscuous and multicast support, multiple transmit and receive queues, support for TCP Large Send Offload, support for TCP Large Receive Offload, support for fast reboot, power management and error recovery and reporting.
The cloning character-special device, /dev/vxge, is used to access all Neterion X3100 10-Gigabit Ethernet devices installed within the system.
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 your DL_INFO_REQ are:
Maximum SDU is 9000.
Minimum SDU is 0.
DLSAP address length is 8.
MAC type is DL_ETHER.
SAP (Service Access Point) length value is -2, meaning the physical address component is followed immediately by a 2-byte SAP component within the DLSAP address.
Broadcast address value is the Ethernet/IEEE broadcast address (FF:FF:FF:FF:FF:FF).
Once in the DL_ATTACHED state, you must send a DL_BIND_REQ to associate a particular SAP with the stream.
By default, the vxge driver performs auto-negotiation to select the link speed and mode. Link speed and mode can only be 10000 Mbps full-duplex. See the IEEE 802.3 Standard for more information.
