40 To compile this driver into the kernel,
41 place the following line in your
42 kernel configuration file:
43 .Bd -ragged -offset indent
47 Alternatively, to load the driver as a
48 module at boot time, place the following line in
50 .Bd -literal -offset indent
53 .Sh DEPRECATION NOTICE
56 driver is not present in
59 See https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more
64 driver provides support for the 3Com
69 can be influenced by the following link flags to the
73 .Bl -tag -width LINK0X -compact
84 driver supports the following cards:
88 3Com 3c590 EtherLink III PCI
90 3Com 3c595 Fast EtherLink III PCI in 10 Mbps mode
93 All other diagnostics indicate either a hardware problem or a bug in the
103 device driver first appeared in
105 It was derived from the
107 driver, from which it inherits most of its limitations.
112 device driver and this manual page were written by
113 .An Fred Gray Aq Mt fgray@rice.edu ,
116 and with the assistance of numerous others.
118 Some early-revision 3c590 cards are defective and suffer from many receive
119 overruns, which cause lost packets.
120 The author has attempted to implement
121 a test for it based on the information supplied by 3Com, but the test resulted
122 mostly in spurious warnings.
124 The performance of this driver is somewhat limited by the fact that it uses
125 only polled-mode I/O and does not make use of the bus-mastering capability
130 driver is known not to reset the adapter correctly following a warm boot
135 driver has not been exhaustively tested with all the models of cards that it
