35 To compile this driver into the kernel,
36 place the following lines in your kernel
38 .Bd -ragged -offset indent
43 Alternatively, to load the driver as a
44 module at boot time, place the following line in
46 .Bd -literal -offset indent
52 driver provides support for the
57 This driver also has quirks preset in the
59 file for card detection.
63 driver supports the following
72 SMC90c66 in '56 compatibility mode.
74 .Sh IMPLEMENTATION NOTES
80 it does not employ the address resolution protocol described in
82 to dynamically map between Internet and Ethernet addresses on
84 Instead it uses the least significant 8 bits of the
86 address as the hardware address
98 encoding is done according to
101 that is, with Packet Header Definition Standard header and packet type
108 flag is cleared by default.
116 encoding is done according to the deprecated
118 1051 encoding, that is with simple header, packet type 240 / 241,
123 When switching between the two modes, use
124 .Dl ifconfig interfacename down up

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