PPP(4) NetBSD Kernel Interfaces Manual PPP(4)
ppp -- point to point protocol network interface
options PPP_BSDCOMP options PPP_DEFLATE options PPP_FILTER pseudo-device ppp
The ppp interface allows serial lines to be used as network interfaces using the Point-to-Point Protocol (PPP). The ppp interface can use vari- ous types of compression and has many features over the SLIP protocol used by the sl(4) interface. Supported options are: options PPP_BSDCOMP Enable support for BSD-compress (`bsdcomp') com- pression in ppp. options PPP_DEFLATE Enable support for deflate compression in ppp. options PPP_FILTER This option turns on pcap(3) based filtering for ppp connections. This option is used by pppd(8) which needs to be compiled with PPP_FILTER defined (the current default).
ppp%d: af%d not supported . The interface was handed a message with addresses formatted in an unsuitable address family; the packet was dropped.
