39 .Nd PCI Ethernet device driver
45 driver provides support for the 3Com 3c590 and 3c595 EtherLink III and Fast
46 EtherLink III PCI Ethernet cards in 10 Mbps mode. The medium selection
47 can be influenced by the following link flags to the
51 .Bl -tag -width LINK0X -compact
61 .It "vx%d: not configured; kernel is built for only %d devices."
62 There are not enough devices in the kernel configuration file for the number
63 of adapters present in the system. Add devices to the configuration file,
64 rebuild the kernel, and reboot.
67 All other diagnostics indicate either a hardware problem or a bug in the
70 Some early-revision 3c590 cards are defective and suffer from many receive
71 overruns, which cause lost packets. The author has attempted to implement
72 a test for it based on the information supplied by 3Com, but the test resulted
73 mostly in spurious warnings.
75 The performance of this driver is somewhat limited by the fact that it uses
76 only polled-mode I/O and does not make use of the bus-mastering capability
86 device driver first appeared in

90 driver, from which it inherits most of its limitations.
95 device driver and this manual page were written by
96 .An Fred Gray Aq fgray@rice.edu ,
99 and with the assistance of numerous others.
103 driver is known not to reset the adapter correctly following a warm boot
108 driver has not been exhaustively tested with all the models of cards that it
