a networking question

[Ashmi Bhanushali]

hi all..

i m a new bee in lunix kernel. and i m trying to implement "FIFO+"
queuing for packet forwarding in linux kernel by modifying the
original code for packet forwarding(FIFO).

i m going to use fedora core 2 and the kernel version is 2.6.11-7. i
need some help to locate the original code of queuing (FIFO). I looked
at some files like ip_input.c, ip_output.c and ip_forward.c in the
net/ipv4 directory of the kernel source code. but i m not sure if
these are the correct files to look for the original FIFO packet
queuing implemented in linux kernel.

could someone please help me in locating the files which has the FIFO
queuing code.

thanks in advance.
