41 To compile this driver into the kernel,
42 place the following lines in your
43 kernel configuration file:
44 .Bd -ragged -offset indent
53 Alternatively, to load the driver as a
54 module at boot time, place the following line in
56 .Bd -literal -offset indent
62 driver provides support for USB Ethernet adapters based on the ASIX
63 Electronics AX88172 USB 2.0 chipset.
65 The AX88172 is a USB 2.0 device which contains a 10/100
66 Ethernet MAC with MII interface and is designed to work with both
67 Ethernet and HomePNA transceivers.
68 The AX88172 will operate with
69 both USB 1.x and USB 2.0 controllers, however performance with 1.x
70 controllers will be limited since the USB 1.x standard specifies a
71 maximum transfer speed of 12Mbps.
72 Users with USB 1.x controllers should therefore not expect to actually
73 achieve 100Mbps speeds with these devices.
75 The AX88172 supports a 64-bit multicast hash table, single perfect
76 filter entry for the station address, all-multicast mode and promiscuous mode.
78 received and transmitted over separate USB bulk transfer endpoints.
82 driver supports the following media types:
83 .Bl -tag -width ".Cm 10baseT/UTP"
85 Enable autoselection of the media type and options.
86 The user can manually override
87 the autoselected mode by adding media options to the
94 option can also be used to enable
103 Set 100Mbps (Fast Ethernet) operation.
106 option can also be used to enable
118 driver supports the following media options:
119 .Bl -tag -width ".Cm 10baseT/UTP"
121 Force full duplex operation.
122 The interface will operate in
123 half duplex mode if this media option is not specified.

150 .It "axe%d: watchdog timeout"
151 A packet was queued for transmission and a transmit command was
152 issued, however the device failed to acknowledge the transmission
153 before a timeout expired.
154 .It "axe%d: no memory for rx list"
155 The driver failed to allocate an mbuf for the receiver ring.
