+.Pp
+The AX88172, AX88178, and AX88772 are USB 2.0 devices designed to work with
+either Ethernet or HomePNA transceivers.
+The AX88172 and AX88772 contain 10/100 Ethernet MACs with MII interfaces.
+The AX88178 contains a 10/100/1Gb Ethernet MAC with a GMII/MII
+interface.
+All adapters will operate with either USB 1.x or USB 2.0 controllers, however
+performance with 1.x controllers will be limited since the USB 1.x standard
+specifies a maximum transfer speed of 12Mbps.
+Users with USB 1.x controllers should therefore not expect to actually
+achieve 100Mbps speeds with these devices.
+.Pp
+A 64-bit multicast hash table is supported,
+single perfect filter entry for the station address,
+all-multicast mode, and promiscuous mode.
+Packets are
+received and transmitted over separate USB bulk transfer endpoints.
+.Pp
+The
+.Nm
+driver supports the following media types:
+.Bl -tag -width "autoselect"
+.It autoselect
+Enable autoselection of the media type and options (this is the default).
+The user can manually override the autoselected mode by adding media
+options to the appropriate
+.Xr hostname.if 5
+file.
+.It 10baseT
+Set 10Mbps operation.
+.It 100baseTX
+Set 100Mbps (Fast Ethernet) operation.
+.It 1000baseT
+Set 1000Mbps (Gigabit Ethernet) operation (AX88178 only).
+.El
+.Pp
+The
+.Nm
+driver supports the following media options:
+.Bl -tag -width "full-duplex"
+.It full-duplex
+Force full-duplex operation.
+.It half-duplex
+Force half-duplex operation.
+.El
+.Pp
+The interface will operate in
+half-duplex mode if no media option is specified.
+.Pp
+For more information on configuring this device, see
+.Xr ifconfig 8 .
+.Sh DIAGNOSTICS
+.Bl -diag
+.It "axe0: watchdog timeout"
+A packet was queued for transmission and a transmit command was
+issued, however the device failed to acknowledge the transmission
+before a timeout expired.
+.It "axe0: no memory for rx list"
+The driver failed to allocate an mbuf for the receiver ring.
