The midway driver has been busdmaified and is not i386-specific anymore.

Browse Source 
Repo-copy it from the i386 specific man4 section to the common one.
Remove the i386 keyword from the man page header.
Document the sysctl interface to the driver.
Fix a spelling error (ALL -> AAL).

.Nd device driver for Midway-based ATM interfaces
.Sh SYNOPSIS
.Cd "device en"
.Cd "device atm"
.Sh DESCRIPTION
The
.Nm
device driver supports Midway-based ATM interfaces including the
Efficient Networks, Inc. ENI-155 and Adaptec ANA-59x0.
Midway is an ALL5 SAR (Segmentation and Reassembly) chip.
.Pp
The driver only supports ATM PVCs. SVC or ATM-ARP is not supported.
.Pp
To configure the card for IP, use something like:
.Dl # ifconfig en0 128.252.200.1 netmask 0xffffff00 up
To add a PVC to a host you must use the ``route'' command:
.Dl # route add -iface <remote IP address> -link en0:z.0.x.y
where x and y are the byte encoding of the VCI to use, and z is the
byte encoding of the following flags.
.Dl 0x01 (use AAL5),
.Dl 0x02 (if using AAL5, use a LLCSNAP header)
Thus, parameter 3 means AAL5 and LLC/SNAP encapsulation.
Note that BPF works only with LLC/SNAP encapsulation.
.Sh EXAMPLES
Suppose you have 2 hosts 128.252.200.1 and 128.252.200.2 connected
by ATM through PVC # 201 (0xc9).
To enable the link use the following commands:
.Dl on host 128.252.200.1:
.Dl # ifconfig en0 128.252.200.1 netmask 0xffffff00 up
.Dl # route add -iface 128.252.200.2 -link en0:3.0.0.c9
.Pp
.Dl on host 128.252.200.2:
.Dl # ifconfig en0 128.252.200.2 netmask 0xffffff00 up
.Dl # route add -iface 128.252.200.1 -link en0:3.0.0.c9
.Sh DIAGNOSTICS

.Ed
.Sh CAVEATS
The driver extensively uses DMA on PCI.
The first
generation PCI chipsets do not work or exhibit poor performance.
