Can you post a copy of the output from "dmesg"? On my Sony VAIO PCG-N505VX
I see the following section from dmesg about my Ethernet card:

ex0 at cardbus0 dev 0 function 0: 3Com 3c575B-TX Ethernet
ex0: interrupting at 9  
ex0: MAC address 00:50:da:99:e6:ae
tqphy0 at ex0 phy 0: 78Q2120 10/100 media interface, rev. 11
tqphy0: 10baseT, 100baseTX, auto

ppp1 is the second ppp network interface available.

sl1 is the second sl network interface available. I think you see how this
goes... you have the network interface name and the number at the end is
the number of that type of interface in the system, starting from 0.

"man 4 strip" reports "strip - Metricom Ricochet packet radio wireless
network device"

"man 4 tun" reports "tun - tunnel software network interface"

"man 4 gre" reports "gre - encapsulating network device"

"man 4 ipip" reports "ipip - encapsulating network device"

Not really sure about this one. There are some references to this in the
directory /usr/src/sys/netinet:

Perhaps someone else could elaborate on this...

Looking at my notes, here are some RFCs that may be of some interest:

rfc1701.txt Generic Routing Encapsulation (GRE)   (obsoleted by 2784????)
rfc1702.txt Generic Routing Encapsulation over IPv4 networks
rfc2003.txt IP Encapsulation within IP
rfc2004.txt Minimal Encapsulation within IP
rfc2784.txt Generic Routing Encapsulation (GRE)
