hi, jus grep in to /net/core/dev.c u find a lot of info on how the packet is beign transmitted to hard_start_xmit of u r Driver regards anand -----Original Message----- From: kernelnewbies-bounce@nl.linux.org [mailto:kernelnewbies-bounce@nl.linux.org]On Behalf Of threadhead@web.de Sent: Wednesday, February 11, 2004 12:30 AM To: kernelnewbies@nl.linux.org Subject: Re: 2.6.x kernels - use of exported symbols/functions > Filling a sk_buff is much related to the > protocols used.
