8 .Nd device driver for Midway-based ATM interfaces
16 device driver supports Midway-based ATM interfaces including the
17 Efficient Networks, Inc. ENI-155 and Adaptec ANA-59x0.
18 Midway is an AAL5 SAR (Segmentation and Reassembly) chip.
20 For configuring the card for IP see
23 The following sysctls are recognized by the driver additionally to those
27 .It Cm hw.atm.enX.istats
30 with internal driver statistics.
31 .It Cm hw.atm.enX.debug
32 This is a bit map of debugging options.
33 This variable is only available when the driver is compiled with debugging
37 The driver supports the media options
46 en0 <Efficient Networks ENI-155p> rev 0 int a irq 5 on pci0:16
47 en0: ATM midway v0, board IDs 6.0, Utopia (pipelined), 512KB on-board RAM
48 en0: maximum DMA burst length = 64 bytes
49 en0: 7 32KB receive buffers, 8 32KB transmit buffers allocated
52 The driver extensively uses DMA on PCI.
54 generation PCI chipsets do not work or exhibit poor performance.
