NAME
sl -- slip network interface
SYNOPSIS
pseudo-device sl [count]
DESCRIPTION
The sl interface allows serial lines to be used as network interfaces
using the slip protocol. The sl interface can use Van Jacobson TCP
header compression and ICMP filtering. This is arranged by using the
various link-level flags to the ifconfig(8) command:
link0 Enable VJ header compression.
link1 Suppress ICMP traffic.
link2 Enable VJ header compression autodetection. This will turn on
the link0 flag as soon as the first VJ-compressed packet has been
seen by the driver.
DIAGNOSTICS
sl%d: af%d not supported. The interface was handed a message with
addresses formatted in an unsuitable address family; the packet was
dropped.
