Sorry if this isn't strictly kernel-related, but I know you guys are the
best equipped to answer this.
(1) I'd like to know what the ioctl() calls are to determine the
encapsulation
for an ISDN interface (rawip, syncppp, cisco-h, etc) from a user-space
program.
(2) I also know that sync ppp interfaces are ippp, but what of the other
types of encapsulations?
(3) How about the spkt_family field after a packet is read from a
SOCK_PACKET socket? What values does it contain for other encapsulations.
I know that sync PPP returns an ARPHRD_PPP, but what of the others.
Thanks for any help. It will be immensely useful to me.
Please reply to this address, as well as to the list (this is a heavy
list, but at least if you include me, my mailer will mark them).
