35 To compile support for the
37 driver into your kernel, place the following lines in
38 your kernel configuration file:
39 .Bd -ragged -offset indent
44 Alternatively, to load the
46 driver at boot time, place the following line in
48 .Bd -literal -offset indent
54 driver provides support for the
59 This driver also has quirks preset in the
61 file for card detection.
65 driver supports the following

82 it does not employ the address resolution protocol described in
84 to dynamically map between Internet and Ethernet addresses on
86 Instead it uses the least significant 8 bits of the
88 address as the hardware address
100 encoding is done according to
103 that is, with Packet Header Definition Standard header and packet type
110 flag is cleared by default.
118 encoding is done according to the deprecated
120 1051 encoding, that is with simple header, packet type 240 / 241,
