NAME

nw − Integrated Solutions, Inc., 10 Mb/s Ethernet controller

SYNOPSIS

NW0 at address 0xF80000/076000000 vector 0xC2/0302 (VME Bus)

DESCRIPTION

The nw interface provides access to a 10 Mb/s Ethernet network through an Integrated Solutions controller. 

The host’s Integrated Solutions address is specified at boot time with an SIOCSIFADDR ioctl.  The nw interface employs the address resolution protocol described in arp(4P) to dynamically map between Internet and Ethernet addresses on the local network. 

The interface normally tries to use a “trailer” encapsulation to minimize copying data on input and output.  This may be disabled, on a per-interface basis, by setting the IFF_NOTRAILERS flag with an SIOCSIFFLAGS ioctl. 

DIAGNOSTICS

nw%d: 100 transmit errors.  Indicates that 100 transmit errors have been recorded (and presumably corrected) since the last time this error message appeared. 

nw%d: 100 receive errors.  Indicates that 100 receive errors have been recorded (and presumably corrected) since the last time this error message appeared.
