37 .Nd Network Systems Hyperchannel interface
39 .Cd "hy0 at uba0 csr 0172410 vector hyint"
41 NOTE: This driver has not been ported from
47 interface provides access to a Network
48 Systems Corporation Hyperchannel Adapter.
50 The network to which the interface is attached
51 is specified at boot time with an
54 The host's address is discovered by reading the adapter status
55 register. The interface will not transmit or receive
56 packets until the network number is known.
59 .It "hy%d: unit number 0x%x port %d type %x microcode level 0x%x."
60 Identifies the device during autoconfiguration.
62 .It hy%d: can't handle af%d.
63 The interface was handed
64 a message with addresses formatted in an unsuitable address
65 family; the packet was dropped.
67 .It hy%d: can't initialize.
68 The interface was unable to allocate
71 is usually due to having too many network devices on an 11/750
72 where there are only 3 buffered data paths.
74 .It hy%d: NEX - Non Existent Memory.
75 Non existent memory error returned from hardware.
77 .It hy%d: BAR overflow.
79 overflow error returned from hardware.
81 .It hy%d: Power Off bit set, trying to reset.
82 Adapter has lost power, driver will reset the bit
83 and see if power is still out in the adapter.
85 .It hy%d: Power Off Error, network shutdown.
86 Power was really off in the adapter, network
87 connections are dropped.
88 Software does not shut down the network unless
89 power has been off for a while.
91 .It hy%d: RECVD MP \*[Gt] MPSIZE (%d).
92 A message proper was received that is too big.
93 Probable a driver bug.
96 .It "hy%d: xmit error \- len \*[Gt] hy_olen [%d \*[Gt] %d]."
97 Probable driver error.
100 .It hy%d: DRIVER BUG \- INVALID STATE %d.
101 The driver state machine reached a non-existent state.
104 .It hy%d: watchdog timer expired.
105 A command in the adapter has taken too long to complete.
106 Driver will abort and retry the command.
108 .It hy%d: adapter power restored.
109 Software was able to reset the power off bit,
110 indicating that the power has been restored.
118 interface appeared in
121 If the adapter does not respond to the status command
122 issued during autoconfigure, the adapter is assumed down.
123 A reboot is required to recognize it.
125 The adapter power fail interrupt seems to occur
126 sporadically when power has, in fact, not failed.
127 The driver will believe that power has failed
128 only if it can not reset the power fail latch after
132 These seem to appear about 2-4 times a day on some machines.
133 There seems to be no correlation with adapter
134 rev level, number of ports used etc. and whether a
135 machine will get these
