34 .Nd "SMC Arcnet Ethernet device driver"
36 To compile this driver into the kernel,
37 place the following lines in your kernel
39 .Bd -ragged -offset indent
42 .Cd "pseudo-device arcnet"
47 driver provides support for the
54 driver supports the following
63 SMC90c66 in '56 compatibility mode.
65 .Sh IMPLEMENTATION NOTES
71 it does not employ the address resolution protocol described in
73 to dynamically map between Internet and Ethernet addresses on
75 Instead it uses the least significant 8 bits of the
77 address as the hardware address
89 encoding is done according to
92 that is, with Packet Header Definition Standard header and packet type
99 flag is cleared by default.
107 encoding is done according to the deprecated
109 1051 encoding, that is with simple header, packet type 240 / 241,
114 When switching between the two modes, use
115 .Dl ifconfig interfacename down up

122 .It "reset: card reset, link addr = 0x%02x (cm%d)"
123 The card is being reset and a new link address assigned.
124 .It "srint: restarted rx on buf cm%d"
125 The rx buffer has been emptied and will be reset.

154 driver code could do with a bit of improvement,
155 it would be nice if some one could come along and take care of this.
