NAME

cue -- CATC USB-EL1210A USB Ethernet driver

SYNOPSIS

device uhci device ohci device oldusb device cue

DESCRIPTION

The cue driver provides support for USB ethernet adapters based on the Computer Access Technology Corporation's USB-EL1210A chipset, including the CATC Netmate and Netmate II, the Belkin F5U011/F5U111, and the Smart- Bridges SmartLink. The USB-EL1210A supports a 512-bit multicast hash filter, single perfect filter entry for the station address and promiscuous mode. Packets are received and transmitted over separate USB bulk transfer endpoints. The CATC adapter supports only 10mbps half-duplex mode, hence there are no ifmedia(4) modes to select. For more information on configuring this device, see ifconfig(8).

DIAGNOSTICS

cue%d: 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. cue%d: no memory for rx list The driver failed to allocate an mbuf for the receiver ring.
