NAME
     lo - software loopback network interface

SYNOPSIS
     pseudo-device loop

DESCRIPTION
     The loop interface is a software loopback mechanism which
     may be used for performance analysis, software testing,
     and/or local communication.   By default, the loopback
     interface is accessible at address 127.0.0.1 (non-standard);
     this address may be changed with the SIOCSIFADDR ioctl.

DIAGNOSTICS
     lo%d: can't handle af%d.  The interface was handed a message
     with addresses formatted in an unsuitable address family;
     the packet was dropped.

CAVEATS
     It should handle all address and protocol families.  An
     approved network address should be reserved for this
     interface.
