26 The values returned by the driver in the DL_INFO_ACK response are:
27
28 o Maximum SDU is 1500.
29
30 o Minimum SDU is 0.
31
32 o The dlsap address length is 8.
33
34 o MAC type is DL_ETHER.
35
36 o SAP length is -2. The 6-byte physical address is immediately
37 followed by a 2-byte SAP.
38
39 o Service mode is DL_CLDLS.
40
41 o The broadcast address is the 6-byte Ethernet broadcast
42 address (ff:ff:ff:ff:ff:ff).
43
44 CONFIGURATION
45 The pcn driver performs auto-negotiation to select the link speed and
46 mode. Link sped may be 100Mbps full-duplex, 100Mbps half-duplex,
47 10Mbps full-duplex, or 10Mbps half-duplex, depending on the hardware
48 adapter type. See the IEEE802.3 standard for more information.
49
50
51 The capabilities advertised by the pcn device can be set using
52 dladm(1m). The driver supports a number of parameters whose names
53 being with en_ (see below). Each of these parameters contains a
54 boolean value that determines if the devices advertises that mode of
55 operations. The adv_autoneg_cap parameter controls whether auto-
56 negotioation is performed. If adv_autoneg_cap is set to 0, the driver
57 forces the mode of operation selected by the first non-zero parameter
58 in priority order as shown below:
59
60 (highest priority/greatest throughput)
61 en_100fdx_cap 100Mbps full duplex
62 en_10fdx_cap 10Mbps full duplex
63 (lowest priority/least throughput)
64
65
66
67 All capabilities default to enabled. Note that changing any capability
68 parameter causes te link to go down while the link partners renegotiate
69 the link speed/duplex using the newly changed capabilities.
