Re: nf_mark use in sk_buff

[shah hemal <hshah127@yahoo.com>]

Dear sir,

     thanks for reply.I have register netfilter hook 
NF_IP_FORWARD and wrote the handler function

 i want to forward the packet from my local buffer
where i have cached it. i saw one field in skbuff
structure. i.e. nfmark.

Is it possible to pass the mark value to module and
then use it to point  skbuff->nfmark?this mark can be
any integer value ??

thanks in advance.
