SYNOPSIS

DESCRIPTION

13       The  myri10ge  Gigabit  Ethernet  driver is a multi-threaded, loadable,
14       clonable, GLD-based STREAMS driver that supports the Data Link Provider
15       Interface,  dlpi(7P),  on  Myricom  Myri10GE  10-Gigabit  Ethernet con‐
16       trollers.
17
18
19       The myri10ge driver functions include controller initialization,  frame
20       transmit  and  receive,  promiscuous  and  multicast  support, multiple
21       transmit and receive queues, support for TCP Large Send  Offload,  sup‐
22       port for TCP Large Receive Offload, and error recovery and reporting.
23
24   Application Programming Interface
25       The  cloning character-special device, /dev/myri10ge, is used to access
26       all Myricom Myri10GE 10 -Gigabit Ethernet dev ices installed within the
27       system.
28
29
30       The  myri10ge  driver is managed by the dladm(1M) command line utility.
31       dladm allows VLANs to be defined on top of myri10ge instances  and  for
32       myri10ge instances to be aggregated. See dladm(1M) for more details.
33
34
35       You must send an explicit DL_ATTACH_REQ message to associate the opened
36       stream with a particular device (PPA). The PPA ID is interpreted as  an
37       unsigned  integer  data  type  and  indicates  the corresponding device
38       instance (unit) number. The driver returns an error  (DL_ERROR_ACK)  if
39       the PPA field value does not correspond to a valid device instance num‐
40       ber for the system. The device is initialized on first attach  and  de-
41       initialized (stopped) at last detach.
42
43
44       The  values  returned  by  the  driver  in the DL_INFO_ACK primitive in
45       response to your DL_INFO_REQ are:
46
47           o      Maximum SDU is 9000.
48
49           o      Minimum SDU is 0.
50
51           o      DLSAP address length is 8.
52
53           o      MAC type is DL_ETHER.
54
55           o      SAP (Service Access Point) length value is -2,  meaning  the
56                  physical  address  component  is  followed  immediately by a
57                  2-byte SAP component within the DLSAP address.
58
59           o      Broadcast address value is  the  Ethernet/IEEE  broad-  cast
60                  address (FF:FF:FF:FF:FF:FF).
61
62           o      Once  in  the DL_ATTACHED state, you must send a DL_BIND_REQ
63                  to associate a particular SAP with the stream.
64
65   Configuration
66       Link speed and mode can only be 10000 Mbps full-duplex.  See  the  IEEE
67       802.3 Standard for more information.
