NAME

       xge - 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:

	   o	  Maximum SDU is 9600.

	   o	  Minimum SDU is 0.

	   o	  DSLAP address length is 8 bytes.

	   o	  MAC type is DL_ETHER.

	   o	  SAP length value is  -2 meaning the physical address component is followed immediately by a  2-byte  sap  component  within  the
		  DLSAP address.

	   o	  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
	      tmac_mcst_frms 6

	      ...

	      rmac_vld_frms 13
	      rmac_fcs_err_frms 0
	      rmac_drop_frms 0
	      rmac_vld_bcst_frms 7
	      rmac_vld_mcst_frms 11
	      rmac_out_rng_len_err_frms 0
	      rmac_in_rng_len_err_frms 0
	      rmac_long_frms 0

	      ...

	      not_traffic_intr_cnt 242673
	      traffic_intr_cnt 28

	      ...
