xge(7D) Devices xge(7D)NAMExge - Neterion Xframe 10Gigabit Ethernet Network Adapter driver
SYNOPSIS
/dev/xge
DESCRIPTION
The xge 10 Gigabit Ethernet driver is a multi-threaded, loadable,
clonable, GLD-based STREAMS driver supporting the Data Link Provider
Interface, dlpi(7P), on S2IO Xframe 10-Gigabit Ethernet Network
Adapter.
The xge driver functions includes controller initialization, frame
transmit and receive, promiscuous and multicast support, TCP and UDP
checksum offload (IPv4 and IPv6), 9622-byte jumbo frame, and error
recovery and reporting.
The xge driver and hardware support the 10GBase-SR/W, LR/W, and ER/W
802.3 physical layer.
APPLICATION PROGRAMMING INTERFACE
The cloning, character-special device /dev/xge is used to access all
Xframe devices installed within the system.
The xge driver is managed by the dladm(1M) command line utility, which
allows VLANs to be defined on top of xge instances and for xge
instances to be aggregated. See dladm(1M) for more details.
The values returned by the driver in the DL_INFO_ACK primitive in
response to the DL_INFO_REQ are as follows:
· Maximum SDU is 9600.
· Minimum SDU is 0.
· DSLAP address length is 8 bytes.
· MAC type is DL_ETHER.
· SAP 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 Ethernet/IEEE broadcast address
(FF:FF:FF:FF:FF:FF).
CONFIGURATION
By default, the xge driver works without any configuration file.
You can check the running-time status of a device instance using
ndd(1M). Currently, the driver provides an interface to print all hard‐
ware statistics.
For example, to print statistics of device xge0:
#ndd /dev/xge0 stats
tmac_data_octets 772
tmac_frms 15
tmac_drop_frms 0
tmac_bcst_frms 6
