A doubt in sk_buff

A doubt in sk_buff

[challaharikumar]

Hi!
all,

A doubt in sk_buff. I am running the fcc_enet driver provided in the PPC
architecture tree for MPC8260 on ADS board.
Kernel version is 2.4.1. The driver has been modified to be loaded as a
module.
When IFNET provides the sk_buff to transmit I store them up in an array
and at transmit complete I release the sk_buff.

When the module is unloaded, I release all the sk_buffs.
When I release the sk_buff I get the following output. Am I doing
anything wrong here ?
----------------------------------------------------------------------------

Any help will be greatly appreciated,
Thanks in advance ,
