Dear Everybody,

	I need to create a program to repeat some data-link frames from an
interface to another one. I use BPF. My program can read the frame
correctly. However, when I write that frame to another interface, the
source ethernet-address is changed from the original one to the output
interface one. I need the frames copied without change. How can I do?

Sincerely yours,
Sunthiti Patchararungruang
