You don't need it since there is only one place to which you can write data, into the port. Well, the problems start when you want to establish X.25 connections. Then you use the X.25 address similarly to a MAC address. But since usually the X.25 connections are static, you set up your table of connections and the translation table between the target IP address and X.25 address, similar to ARP but static. -SB ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"

One other option is to let your driver present a simple serial IO interface and implement higher level logic in a user level daemon that uses a tun device to plug into the network layer (like /usr/sbin/ppp). Also be, sure to read RFC1661! ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Re: help regarding : To recieve and tranmit packet th' an interface
From: "rashmi ns" <[EMAIL PROTECTED]> But we want to tranmit/Rx a real packet in (mbuf structure) and test our code .As it is a HDLC controller does'nt have std MAC ADDRRSS . How can i actually achieve a packet transmition and reception .Are there some drivers which does the same I would think any of the existing drivers for WAN-type interfaces would be facing all of the the same issues as you might.

help regarding : To recieve and tranmit packet th' an interface
Hello List-members, we are writing a driver for HDLC-Controller We have coded upto some extent and actully we are able to transmit and recieve a char buff in loopback (from inside a driver). But we want to tranmit/Rx a real packet in (mbuf structure) and test our code .As it is a HDLC controller does'nt have std MAC ADDRRSS . How can i actually achieve a packet transmition and reception .Are there some drivers which does the same Thanks and Regards, Memeber ___ freebsd-hackers@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
