help regarding : To recieve and tranmit packet th' an interface

[rashmi ns]

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,
