8 .Nd "device driver for Midway-based ATM interfaces"
10 To compile this driver into the kernel,
11 place the following lines in your
12 kernel configuration file:
13 .Bd -ragged -offset indent
19 Alternatively, to load the driver as a
20 module at boot time, place the following line in
22 .Bd -literal -offset indent
28 device driver supports Midway-based ATM interfaces including the
29 Efficient Networks, Inc.\& ENI-155 and Adaptec ANA-59x0.
30 Midway is an AAL5 SAR (Segmentation and Reassembly) chip.
32 For configuring the card for IP see
35 The following sysctls are recognized by the driver additionally to those
38 .Bl -tag -width indent
39 .It Va hw.atm.enX.istats
42 with internal driver statistics.
43 .It Va hw.atm.enX.debug
44 This is a bit map of debugging options.
45 This variable is only available when the driver is compiled with debugging
49 The driver supports the media options
58 en0 <Efficient Networks ENI-155p> rev 0 int a irq 5 on pci0:16
59 en0: ATM midway v0, board IDs 6.0, Utopia (pipelined), 512KB on-board RAM
60 en0: maximum DMA burst length = 64 bytes
61 en0: 7 32KB receive buffers, 8 32KB transmit buffers allocated
64 The driver extensively uses DMA on PCI.
66 generation PCI chipsets do not work or exhibit poor performance.
