40 To compile this driver into the kernel,
41 place the following lines in your
42 kernel configuration file:
43 .Bd -ragged -offset indent
52 Alternatively, to load the driver as a
53 module at boot time, place the following line in
55 .Bd -literal -offset indent
61 driver provides support for USB Ethernet adapters based on the ASIX
62 Electronics AX88172, AX88178 and AX88772 USB 2.0 chipsets.
64 The AX88172 and AX88178 are USB 2.0 devices that contain a 10/100
65 Ethernet MAC with MII interface and are designed to work with both
66 Ethernet and HomePNA transceivers.
67 The AX88772 will additionally support 10/100/1000 MACs.
69 These devices will operate with
70 both USB 1.x and USB 2.0 controllers, however performance with 1.x
71 controllers will be limited since the USB 1.x standard specifies a
72 maximum transfer speed of 12Mbps.
73 Users with USB 1.x controllers should therefore not expect to actually
74 achieve 100Mbps speeds with these devices.
76 All chipsets support a 64-bit multicast hash table, single perfect
77 filter entry for the station address, all-multicast mode and promiscuous mode.
79 received and transmitted over separate USB bulk transfer endpoints.
83 driver supports the following media types:
84 .Bl -tag -width ".Cm 10baseT/UTP"
86 Enable autoselection of the media type and options.
87 The user can manually override
88 the autoselected mode by adding media options to the
95 option can also be used to enable
104 Set 100Mbps (Fast Ethernet) operation.
107 option can also be used to enable
119 driver supports the following media options:
120 .Bl -tag -width ".Cm 10baseT/UTP"
122 Force full duplex operation.
123 The interface will operate in
124 half duplex mode if this media option is not specified.

187 A packet was queued for transmission and a transmit command was
188 issued, however the device failed to acknowledge the transmission
189 before a timeout expired.
