NAME
idt
- device driver for IDT NICStAR-based ATM interfaces
SYNOPSIS
device idtdevice atm
DESCRIPTION
The
device driver supports ATM network interfaces based on the
IDT NICStAR 77211 controller, including the FORE Systems
ForeRunner LE25 and LE155.
For configuring the card for IP see
natmip(4).
ATM CBR connections are supported, and bandwidth is allocated in
slots of 64k each.
Three VBR queues handle traffic for VBR and UBR.
Two UBR queues prioritize UBR traffic.
ILMI and signalling get the higher priority queue, as well as UBR traffic
that specifies a peak cell rate.
All other UBR traffic goes into the lower queue.
The following sysctls are recognized by the driver:
hw.idt.log_bufstat
Print statistics about buffer use to the system log periodically.
hw.idt.log_vcs
Print information about VC opens, closes, and other events to the system log.
hw.idt.bufs_large
Set or print the maximum size of the 2KB buffer queue.
