Entrega NET-USB-E45 and NET-HUB-3U1E, the ATen UC10T, the Netgear EA101,
the D-Link DSB-650, Corega USB-T and the SMC 2102USB and 2104USB.
.Pp
The KL5KLUSB101B supports a 128-entry multicast filter, single perfect
filter entry for the station address and promiscuous mode.
Packets are
received and transmitted over separate USB bulk transfer endpoints.
.Pp
The Kawasaki adapter supports only 10mbps half-duplex mode, hence there
are no
.Xr ifmedia 4
modes to select.
.Pp
For more information on configuring this device, see
.Xr ifconfig 8 .
